Hello,
i would like to compare the Optistruct Topology optimization and the new Ansys Topology Optimization in relation to the optimization result.
At first I would like to compare the results of the two solver with the minimum compliance as objective.
I plan to run several optimizations with 90, 80, 70 … 10% as volume constraint.
The result should be a graph with the volume on the x-axis and the compliance on the y-axis. Each run is one point in the graph.
Now to my problem:
I thought the results are in a comparable range, but the values are very different. For example, the result of the last iteration with 20% Volume constraint:
Optistruct Compliance: 858 Nmm
Ansys Compliance: 4153Nmm
It is exactly the same part. The result is relative to the displacement is also comparable.
Now I doubt whether it is really useful to compare the results with the compliance.
Are deviations of this magnitude realistic? Makes it sense to use the compliance for comparison in your opinion, or do you know a better possibility?
Thank you very much
Andreas
