Ansys Maxwell Mesh

Aliosha86 · August 13, 2019, 03:48

Hi guys,
I am trying to solve a transient problem in Ansys Maxwell. I would like to import the mesh from the magnetostatic problem to the transient one.
Anyone can help me?
Cheers,

Hi Alessio,

In workbench you can simply drag and drop the model cell (where the mesh is contained) to the model cell of the transient setup. This will copy over the mesh for your new analysis.

Have fun

Thank you Gweher,
I appreciate a lot.

Hi Gweher,
do you think it is possible to import the mesh from Maxwell to ansys mechanical?And do you know how?
Cheers,
Alessio

Hi Alessio,

I think that that is unfortunately not possible. The meshing in magnetostatic and eddy current solvers in Maxwell adaptively refine the mesh until convergence is reached. You can copy the mesh between analysis within Maxwell for instance but there is no direct export option.

If you couple it to a transient structural you can import the forces for instance but not directly extract the mesh data from Maxwell.

Maybe if you pass through the FE modeller it may be able to extract some data. Otherwise I have no other idea.

Thank you Gweher,
I appreciate a lot. I was doing what you suggested and I thought it was an easy way to import the same mesh from Maxwell to Mechanical.
Yeah, the distribution of forces that I import is the same as in Maxwell and this is good.
Anyway, they are in N/m3 and not in N. Is there any easy way to convert them?

As far as you know, when you perform a transient simulation in Maxwell and you import the outputs(Volume forces or Heating generation due to eddy currents) in "Transient Structural" or "Transient Thermal" does it import all the time forces or eddy currents evaluated for the specific time step in Ansys Maxwell?
Or do I have to specify the specific time steps?

Cheers,
