Direct Optimization

      Hello,nPLease help me with the following issue:nI am doing a direct optimization for a structural, linear static problem. The convergence is reached. When I replace the value for the only parameter considered in the original model, I get values that do not matche the optimization result.nTo be mode specific, my objective is that the equivalent stress-290 [MPa] is zero, with only a parameter (a thickness). When I replace the value for the thickness obtained after the optimization, the equivalent stress-290 is more than 30 MPa, instead of the -2MPa obtained after the optimization.nMany thanksnIonutn

      Please show screen snapshots of the model, the parameter, the output, the optimization tables, etc and if you can, create a .wbpz file, put that in a zip file, and if it is < 50 MB, you can attach that to your reply where you must also state the version of Ansys you are using. If the file size is too large, Clear Generate Data on the Mesh, save and archive and it will be smaller.n
