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 Mjunk, There are some warnings about illegal triangles after surface tesselation and some other issues with the geometry in general. As you created this project 4 days ago, you most likely have not the latest version of the geometry. Import the Homework Project again from the first post and you …

I have already completed a simulation with wrong results due to bad mesh quality. Do I need to redo the homework for correct results?

@Milad_Mafi @Akrem @ahmedhussain18

Hi, If you have run the simulation with the older mesh for End Time = 6,000 (See section ‘Simulation Control’), then your results should be fine and you can submit. This is because the older mesh requires more iteration to converge due to bad quality . If not, then you could change End Time to 6,…

hello, I don’t know why the meshing operation fails. I’ve tried to run the meshing operation with 32 and 16 cores. The last lines of the “Meshing logs” are the following. Any suggest? After refinement surface refinement iteration 6 : cells:3503108 faces:11727465 points:4788021 Cells per refineme…

@Ali_Arafat I tried to rerun the simulation with end time = 6000 but it has been cancelled and it stops at 2800 sec. The results are quite similar to those obtained in the tutorial. Why has the run been stopped?

Hi @vlupi Your run was cancelled because the “Maximum execution time” that was specified in Simulation Control was exceeded. The “Maximum execution time” (which is Not the simulation end time) is the maximum real clock time for the run. It is used mainly as a safety feature to limit usage and save…

Dear SimScale team,

while working I got the following message:
