Workbench Mechanical: Animation of static structural solution does not oscillate

Workbench Mechanical: Animation of static structural solution does not oscillate

Workbench Mechanical: Animation of static structural solution does not oscillate

(OP)
Hello

After updating from Ansys 14.5 to Ansys 15, the behavior of the "Graph"-animation has changed for the worse.
While in Solution, the increase in stress and deformation works its way up to time=1, but instead of gradually working its way backward and down to time=0 again, it jumps straight to 0 and starts gradually going up to 1 again.

I know it's a minor issue , but I can't for the life of me figure out why it does this. It's harder to concentrate on the stress distribution when it keeps jumping like that.

The documentation states as follows:
For a static simulation, the progression of an animation occurs in a linear forward/backward manner. The color contours begin with the initial condition, advance to the solution state, and then “rewinds” to the initial conditions.
For transient and stepped simulations that have an associated time or step range, the animation begins at the initial time or step value, progresses to the final set, and then stops and starts at zero again. It does not traverse backward as it does for static simulations.


Why is my static simulation not traversing backwards as well?
This picture shows the simple load and boundary setup:



It does this on other static models too.

Hello Nougatti,

Since, as you quoted this, the doc says : "For a static simulation, the progression of an animation occurs in a linear forward/backward manner. The color contours begin with the initial condition, advance to the solution state, and then “rewinds” to the initial conditions.", I guess you're probably facing a bug.

I would try to contact support if I were you.

Update:

Contacted support. Got the following answer:
This is now a known defect 88542 and will be corrected back in the next release. Thanks for reporting.

In the meantime, it seems that this is a common problem and that all my ANSYS-using coworkers have the same issue.
I also noticed that it oscillates properly if I animate when viewing reactionary forces or if I do a buckling-analysis.
