Newby: how to solve simple 2D electrostatic problem

Post by Gumersindo »

I just started to work with FEM software and I know basically nothing, so I apologize if my question is stupid.

I want to calculate the E field created by 4 plates at potential +V and -V in the space between the plates. I don't even know if I can define the position of the plates in Elmer, so I tried by defining my system in FreeCAD and exporting it as a .step file (following some tutorial online). By doing this I get the error: "The mesh generators of ElmerGUI are currently unable to handle cad files with multipole shapes. Please consider using external software for mesh generation in this case."

This is what I want to do:
1) Define the plates in the space.
2) Set constant voltage in each one of them.
3) Calculate x and y components of the electric field in the plane of the plates.
4) Generate a .dat file or similar with the values of both components as a function of the x and y coordinates.

I don't even know how to start, so any advice is welcome.
