Set specific element size for one part

[Maschinenausleger]

Hi, everybody.
I am new to pyleecan and I have a new project where I need to adapt element size for a specific part of the machine (Rotor). I saw in the tutorial the opportunity to specify the air gap element size via the femm_dict_enforced. I assume that this should also work for the rotor. unfortunately I can't figure out how to access the rotor. Has someone an idea how to solve this problem?

Thanks in advance
Chris

Hello,

Thank you for your interest in pyleecan. The mesh size of each part is computed in: pyleecan\Functions\FEMM\comp_FEMM_dict.py
When running a simulation, the full FEMM_dict is saved in out.mag.internal.FEMM_dict. So you can run a simulation with Nt_tot=1, get the generated FEMM_dict and check the content to find which key you need to set. I assume it will be something like FEMM_dict["mesh"]["Rotor-0"]["meshsize_magnet"] for instance.

On a side note you can also use simu.mag.Kmeshh_finess to change the mesh size for all the machine.

Best regards,
Pierre

Hi, thanks for your quick response.
I was exactly what I was looking for.
