Topology Optimization queries

[AlanSYH_]

Hello guys!
I was playing around the TO parameters and I got this result using these parameters.
Parameters:
Objective Minimize SE, constraint <=30% volume fract. & max member thickness 30mm


With the same setup, I changed the VF constraint to 50% and Max Member Thickness on two separate instances respectively & now it gives an abortion error ‘success check string was not found in the solver output file’. Attached below is the error prompt.



I have no idea why this is happening. Any advices would be greatly appreciated!

Sorry if it is confusing, I meant that I changed the volume fraction constraint to 50% and it gave the error mentioned above. Then I tried to change the max member thickness to 20mm from the original 30mm & I got the same error.

I think all 4 lines basically just saying the optimisation failed.

Yeah I know, I’m looking to troubleshoot it. The only thing that I changed was the volume fraction from 30% to 50%. I don’t get why it’s giving this error or why.

You'll probably find a more informative message in a log file or output file.
