Modeling superconductors in AED

  Hi, to extend the modeling capabilities of Ansys one could add extra equations to be used by the solvers, right? My question is about how to do that. I want to model devices made with superconducting materials, but superconductivity is not correctly modeled by the Maxwell equations used in Ansys Maxwell. For example, The London equations could be used instead of the Maxwell equations to model perfect diamagnetism. Could someone indicate how to make Ansys Maxwell use other equations?
  
  Thanks!
  
  PS. I am new to Ansys and only have access to the AED Student version 2022

  Hi Luis,
  A possibility is to work with the material thresholds in the Design Settings dialog box, which tells the Maxwell solvers how to deal with conductors and insulators. Materials with conductivities above the Perfect Conductor threshold are treated as having infinite conductivity and surface current only, while materials with conductivity values below the Insulator/Conductor threshold are treated as insulators with no conductivity and no current carrying capability.
  You can partially influence the solver using Control Program located in the Analysis/ Setup. This requires certain expertise, and it is not available in all the solvers. You can find detailed information in the Maxwell Help.
  I hope this helps.
