I am trying to do a simulation of an expansion tank and the first version there was no problem to get a result but then I noticed the bad quality of upper part do I did the mesh for upper part again, the rest I remain the same but this time when I try to run the simulation the log tells that the warning of # 3079 like always. At first I think maybe because I need to update all the setting conditions including contact and loads conditions but it did not work and then I wonder if I have changed the meshing of one part then the connection of meshings of two parts would be missing so I need to do meshings for two parts together?
