Progress simulation

    • bagusyn

      Hello!! I have problem when solving the model use meshing elemen size 0,3mm but when I run the model using elemen size of 1 – 0,4 mm it work completely done the progress show 100%, but when I change the elemen to 0,3 mm the progress only done 11%, like what it show in the screenshot. Please help me if that something wrong with the model or spec of my pc

      Please the solution looks completed. Is the snapshot with 3mm mesh size?

      Which ANSYS Release are you using?
      Were you running your model with HPC (Distribute Solve)? If yes, how many cores were you using?
      The computer configuration in your post shows 16 cores in your computer. If you were running your model using 16 cores, can you try 8 cores or 12 cores?
      The problem you observed may be related to the problem with data synchronization in HPC between different cores. Reducing the number of cores used in HPC will improve the data synchronization between cores. We have fixed the similar issues in the few releases ago. Using the latest release of ANSYS 2022R1 if possible.
