Hello Everyone, @varunsura , @PhilippB94 , @durgesh786 , @agupta , @fhnx , @LoganZundel , @slibbi , @kianz89 IMPORTANT NOTE: for all who are facing issue of strange simulation results e.g the figure below [image] What was causing this ? The reason for this was a lot of illegal cells ( bad quality …

Hi @varunsura , @fhnx , @LoganZundel Your solutions are not fully converged. You’ll need to run about 6000 iterations in order to get an acceptable solution. If you take a look at any of the force results, you’ll see that there are still strong variations. [image] The more iterations you run, the…

I started the meshing of the model and it failes giving me the following errors “Illegal triangles were found after surface tesselation. There could be a problem with the CAD geometry. Trying to proceed anyway.” “The tesselated surface is not closed. There could be a problem with the CAD geometry …

I have exactly the same problem. I tried to restart the meshing and now it’s working but it took a lot of time.

Hi, I have some problems doing the mesh. In the meshing log I got the error: (25): ERROR: dgraphFold2: out of memory (2) What does this mean? The link of my project is https://www.simscale.com/workbench?publiclink=5f9f4073-425c-48fc-8203-32d3431562f6 Thank you for your help!

I am having this problem during the run of the simulation The job execution was aborted, possibly due to a numerical instability. Review the log to identify reasons: unphysically large field values, extremely small time step size, etc. Modifying numerical settings and time step size could resolve t…

Hi @melia , Have you tried with the latest version of the geometry? If you are not sure, Import the Homework Project again from the link in the first post. I had no issues with the STL. Cheers.

@Akrem @pfernandez Hey! I’ve had the same problem as @varunsura @fhnx @LoganZundel However, I checked on the convergence plots as you suggested. My results seemed to have converged. Any further suggestions? My project for review: SimScale Login Log in to your SimScale account. SimSc…

Hi, your sim did not converge. You have to zoom in on the graphs to get rid of the big deviations from the beginning.

I can’t find the 3rd confi model in the imported file. Do we have to complete only one model i.e.1-2 confi?
