### A Simple System based on Salome for Solving Electromagnetic Problem

In the system boundary, materials and source are assigned to the geometrical model, after that a conformal mesh can be automatically generated in the background, the boundary, materials and source are also adopted to the mesh.

Still have some problems in post processing.

Are you interested in starting this work as an open source project? If so, I will try to contribute.

Hi,

which solver do you use?

Matthias

The solver is developed by myself based on the discontinuous Galerkin time-domain method.

Thanks, I'll consider to share this work in the future.

Posted by Rick Chen at July 18. 2017Hi Matthias,

Thanks for your suggestion. Current I only focus on DGTD method, and it's hard to find an open source solver of electromagnetics which satisfies my needs. Usually thoes open source solvers are enough for academic, but for industrial usage they still need a lot of time to do the secondary development.

I am not so deep in the FEM maths, so I cannot tell if Elmer works exactly the way you need. AFAIK Elmer is also used in the industry and can compete with commercial solvers like Comsol in quite some areas. And it's open source, so everyone is free to extend and optimize it. To find out if Elmer suits your needs, you could check in the description in the Solver Manual (http://www.nic.funet.fi/pub/sci/physics/elmer/doc/ElmerSolverManual.pdf), section 1.3.3, or directly with the developpers on the forum (www.elmerfem.org/forum).
