What are the differences between the new symbolic engine in Mathcad Prime 6.0 vs the legacy symbolic engine used in earlier versions? Here’s some information for those of you who are wondering.

New Symbolic Engine in Mathcad Prime 6.0

PTC Mathcad Prime 6.0 uses a new symbolic engine that replaces the legacy symbolic engine used in earlier releases of PTC Mathcad Prime (such as Mathcad Prime 5.0, Mathcad Prime 4.0, and earlier versions).
 
The new symbolic engine released with PTC Mathcad Prime 6.0 is used by default now when creating a new worksheet or when opening a new worksheet from an earlier version of the software.
 
When opening a worksheet created in an earlier release of PTC Mathcad Prime contains symbolic evaluations, the following message appears:
 
This document was created with a prior version of PTC Mathcad Prime and contains symbolic evaluation. PTC Mathcad Prime 6.0.0.0 uses new symbolic engine and results of symbolic evaluation may look different. Read more about symbolic engine changes.
 
The above message also appears when you open a converted worksheet that contains symbolic evaluations.
 

Switching Between Symbolic Engines

You can revert to the legacy symbolic engine that was available in earlier versions than the new PTC Mathcad Prime 6.0 at any time. PTC is allowing this in the Mathcad 6.0 version and the Mathcad 7.0 version, then the legacy symbolic engine will be no longer be accessible with Mathcad 8.0.
 
If you’d like to access the legacy symbolic engine, just follow these steps:
1. On the Calculation tab, click Calculation Options > Legacy Symbolic Engine.
2. On the Calculation tab, click Calculate to see the results of switching to the Legacy Symbolic Engine.
 
Clicking the Legacy Symbolic Engine switches between the symbolic engine in PTC Mathcad Prime 6.0 and the legacy symbolic engine in earlier releases of PTC Mathcad Prime. When the legacy symbolic engine is selected, the status bar displays .
 
It is recommended to use the symbolic engine introduced in PTC Mathcad Prime 6.0.0.0 when creating worksheets. The legacy symbolic engine will be deprecated in a future release.
 

Differences Between the Legacy and New Symbolic Engines

We would like to be as transparent as possible with the differences between the legacy and new symbolic engines: Here are some things you should be aware of.

Assumes that undefined variables in the evaluated expressions are real.
Assumes such variables are complex.
Differences in evaluation. Results remain mathematically correct under assumptions made.
Assumes that undefined input arguments are real, but it accepts defined arguments in the form of a+b*1i or 2+5*1i.
Assumes such arguments are complex.
Differences in display of evaluation. Results remain mathematically correct.
In many cases, formulates evaluation results in a different way such as in the order of arguments and other visual differences.
Evaluate ex, specify the keyword series, and compare the result by the two engines.
Differences in display of evaluation. Results remain mathematically correct.
Returns results that are mathematically accurate even if they look different than what the legacy symbolic engine returns.
Evaluate Ai(z)/Ai.sc(z) and compare the result by the two engines.
Differences in display of evaluation. Results remain mathematically correct.
When using the symbolic keyword “float, n” to specify the precision of floating-point calculation results:
• Variable n can be any positive integer.
• The displayed value is the result of rounding-up the selected digits.
When using the symbolic keyword “float, n” to specify the precision of floating-point calculation results:
• Variable n can be any positive integer between 1 and 250.
• The displayed value is the result of rounding-down the selected digits.
• No limit on digits used with keyword float.
• Rounding difference.
Some evaluations of symbolic expressions that were not supported in the legacy symbolic engine are supported in the new symbolic engine. Evaluations of some symbolic expressions that were supported in the legacy symbolic engine are not supported in the initial release of the new symbolic engine but will be added in future releases.
Some evaluations that previously didn’t provide a result will now provide a result. Some evaluations will not provide a result in this first release but will be added in a later release.

About Symbolic Calculation

You can perform operations on symbolic expressions that contain variables or mathematical symbols and PTC Mathcad returns the results in symbolic form.
 
Symbolic evaluation of functions is not supported inside solve blocks.
In symbolic calculation, expressions are evaluated using the symbolic evaluation operator → rather than the numerical evaluation operator =.
 
You can evaluate all of the standard PTC Mathcad operators and many built-in functions symbolically.
 
The benefits of using symbolic evaluation of expressions follow:
• Unlike the numerical evaluation, with symbolics you can evaluate expressions without assigning values to variables.
• Symbolic results can reveal relationships among variables that might not be apparent from numerical results.
• Symbolic calculations are immune to the round-off errors that are inherent in numerical calculations.

We’re all challenged to get as much work as possible done within limited timeframes. One of the easiest ways for engineers and designers to get more done is by re-using design knowledge. I understand the obstacles between reuse. It can be difficult to capture and re-use engineering and design knowledge when captured on whiteboards, notebooks, and napkins. The ideal process takes advantage of effective and efficient knowledge capture using tools digital like Mathcad to communicate:

  • Design intent
  • Engineering critical values
  • Optimized parameters
  • Compliance with performance
  • Validation analyses

FAQ

Can a Mathcad Prime file be opened in Mathcad Express?

Mathcad worksheets that are created with the fully licensed version of Mathcad Prime can be opened in Mathcad Express. In MC Express, edits can be made to the text. In MC Express, any edits made to the math that utilizes a premium feature will issue a message to the user indicating that the feature requires a license. Math created with premium features will not calculate in MC Express. Accordingly, math created with Express/non-premium features will in-fact recalculate in MC Express.

PTC’s Technical Specialist for Mathcad, Anji Seberino, joined us on today’s webinar called “Plotting Your Success with Mathcad Prime 5.0” to demonstrate how 2D plots have evolved in PTC Mathcad. This information technology and leading engineering calculations software is the number one tool for designers and engineers in the industry. Download the PTC Mathcad Prime 5.0 brochure.

Let’s talk about plots. PTC listened to their customers and responded to suggestions and requests needed for Mathcad Prime. The old plotting method is still available for those that need to use it, although the new improvements gave plots the abilities to add a title, a legend, gridlines, axis labels, a 2nd y-axis, and richer formatting options. 

Anji demonstrates how you can calculate stress using input variables of force and area on your Mathcad worksheet:

 calculating stress in Mathcad | EAC Product Development Solutions

The original way to create a plot in PTC Mathcad Prime 4.0 was to go to the ‘plots’ tab and click ‘insert plot’ – this function is still here.

With the old way (which you can still use), you would follow these instructions:
-insert plot
-x-axis= force
-y-axis= σ2

2D plot chart in Mathcad | EAC Product Development Solutions

You can see that ‘force’ and ‘σ2’ are names of variables that store our mathematical data – but they are NOT labels. You cannot add the labels using this old method (but you can with the new).

The new way is NOT on the plots tab – it’s on the math tab – called the ‘chart component’.

-go to ‘math’ tab
-click on ‘chart component’
-right click on the chart, click on ‘insert x-axis expression’
-right click on the chart, click on ‘insert y-axis expression’

On previous version of Mathcad you could not enter a 2nd y-axis. Now you can:
-right click on the chart, click on ‘insert y-axis expression’

In the chart component you can access all the rich format options in one place with a lot more room to make the plot the way you want it to look with styles, the legend, a title and where you’d like the location of all of these components to be while being able to change background, text, and line colors, borders, and opacity settings.

PTC Mathcad helps you calculate and solve engineering problems. Much more can be done in charting your 2D plots in Mathcad Prime 5.0 – watch the webinar replay here.

 

PTC Mathcad Prime delivers powerful engineering calculation management to help predict design behavior, drive critical parameters and dimensions, and enhance the visualization of your data with 2D plotting. Since there was a lot of feedback from users that there needed be improvements to the plotting features in previous Mathcad releases, Mathcad Prime 5.0 is almost entirely focused on enhancements to 2D plots.

New Capabilities of Mathcad Prime 5.0

The new capabilities dramatically improve user’s ability to customize the look and layout of their charts and graphs to better convey information to stakeholders. Prime 5.0 adds a new button under the Math tab called the ‘Chart Component.’ The plots tab will look the same as previous versions of Mathcad because nothing has been removed, only augmented for the addition of the new chart component.

Previous to the new release, users were unable to fully control a title, a legend, gridlines, a 2nd y axis, or custom formatting when creating a plot graph under the plots tab. These capabilities are now available in Mathcad Prime 5.0!

Using the new ‘Chart Component’ in Mathcad

Insert a chart component under the math tab – this will insert an empty embedded charting object. If you double click on it, then you can activate the charting application.

This image shows users the activated charting application once the embedded object is double clickedThis image shows users the activated charting application once the embedded object is double clicked.

The user can now access all the functionalities of the application that help customize the chart under the plot tab, the x tab, and the y tab such as the title, a border, gridlines, a legend, font, and colors.

Once you close this tab you will see your document again and notice that there is an area above your chart component that says ‘Inputs’. This is where you define the data or function that is needed for the chart to be plotted. You can define either functions or variables that store data. If you click on this section you will see a dropdown of various options in which you can choose to either ‘Insert X-Axis Expression’ or ‘Insert Y-Axis Expression’.
