  Hello, I tried to solve a topology optimization analysis and used two version of ansys ( 18.1 and 18.2 ). I always get same errors;
  - '' current result file may not contain requested result data C:UsersIBODesktopAnaliz2topology_filesdp0SYS-8MECHfile;topo. Please clear the solution ''
  - '' The optimization solution run was terminated. Check the optimization output on the solution information object for possible causes ''
  Can anyone help me to find out a way ?

  Hello Mr. Aniket, I realized a big mistake that I've done in this analysis. I forgot to give the density of my newly defined material. Even if I solve my problem this analysis takes a lot of time like more than 3 hours. I've done the same analysis before and it was taking around 30 minutes. I don't understand the problem of time. Do you have any idea about the processing time?
