I am having trouble meshing a somewhat simple solenoid in COMSOL, more specifically, solenoids with a small pitch. I have attached a simple solenoid simulation (created in 4.2) which demonstrates the problem I am having. In this file I am trying to calculate/visualize the flux generation of different solenoid models with a specified current input.
When the pitch of the solenoid is small then I COMSOL will give me a mesh warning or error when generating the free tetrahedral mesh around the solenoid. If you look at the model, you can see COMSOL is having trouble generating the mesh at the input/output of the solenoid. COMSOL has no problem creating a mesh when the pitch and minor radius are increased.
I was able to create a swept mesh based on a free triangular pattern but I found I was unable to create a free tetrahedral mesh around the model (for the 'air' box representing the boundary conditions).
Does anyone know why I might be getting these meshing errors and any suggestions as to what I could try next?
