Magnetic field
Posted: 11 Oct 2023, 23:43
Hello,
I'm discovering elmer and I'm trying to start a simulation to see magnetic field generated in a metallic case by a lightning in a lightning conductor.
I have built Elmer, ElmerGUI and ElmerPost on my Linux Devuan (testing) workstation and I have read a lot of documentation and I'm not sure I understand how Elmer runs.
In a first time, I have exported my case into a STL file from my CAO software (FreeCAD). In a second time, I have given this STL file to gmsh to obtain a new mesh file I can open with ElmerGUI
In a first time, I consider my case is in pure copper.
Now, I want to add a stimulus (lightning conductor with a 8/20µs wave) and I want to configure Elmer to run a simulation. I don't understand how to add lightning conductor. Should I add conductor in the mesh file (with my case) ? And if I have to add this conductor in mesh file, I have a dielectric support between conductor and case. I have tried to configure three bodies (case in pure copper, support in polyacrylic and conductor in steel) without success.
Help will be welcome.
Best regards,
JB
