I am attempting to run a basic topology optimization run.  The analysis is a simple test case based on this youtube video:

Static structural works fine but when attempting to run the topology optimization, I get a couple errors.  In Workbench it says "Update failed for the Setup component in Topology Optimization.  Unable to update setup.  Unable to write APDL input file." 

Then in Mechanical it says "An error occurred  inside the SOLVER module: general error."

Thoughts on what might be wrong?

Hi,

Please see if the following post helps: Error-Unable to update setup. Unable to write APDL input file. (ansys.com)

Hi Ashish,

Unfortunately no.  Following that link, Nanda Veralla suggests to:

1. Go to the Start Menu and open %temp% folder. Search for ‘.ansys’ folder and rename it to ‘.ansys.old’ then launch the application. 
2. Open a file explorer and type %appdata% in the address bar.

     Locate the Ansys folder --> select version (V231) and rename it to V231.old

I did #1 but when tried #2 I could not find an ansys folder in appdata.

So I tried rerunning it after renaming .ansys to .ansys.old, but same error.

I am using 2019 R3 by the way.

I then followed Gary Stofan's link that is linked on that site.  I tried retaining design points.  I went to "Tools > Options > Appearance…scroll down to “Beta Options” and check the box".  Then made some parameters like maximum stress and followed the instructions to retain design points.  But that didn't help.  Same error.

I also did not find a file with the name ansyswbdumpfile.dmp.

 

Still looking for help getting this basic run to work!
