I will be more specific here. I am trying to simulate a two dimensional mhd flow through an MPD thruster. I have the euler equations with coupled electric and magnetic field. I prefer using opensource products and I am comfortable with python and fortran. I want to know if a mesh from gmsh or netgen could be directly used for the code. I have written codes only using basic fdm. I haven't even written any complex fvm codes. But I am planning to develop three codes using mhd, DSMC and PIC methods. And I am not an expert in any of these. I am conducting experiments too although I don't need any help in that part. I would really like some expert input on the problem that I have on hand. Expecting some good answers.
