Can I compute the following in WB Mechanical with expressions?:
I need to calculate the 'u' variable along a line specified as a path geometry (placed along the centroid axis of a rectangular body). Computing u requires integrating TG over time. I would like a plot of the variable across this line. Then I would like to plot that line at multiple times on the same graph. In the example below (not shown in this KB Solution) u vs. distance is plotted every 30min during my transient cool down simulation. I do something similar in COMSOL multiphysics but I'd like to see if I can also implement this into Ansys workbench.
This can be done with a Solution Commands Object as shown below. ! ****** Begin Command Snippet ****** !
