electric and magnetic fields

Please login with a confirmed email address before reporting spam

hello, when i use the mef module electric fields in the geometry work fine but when i additionaly try to give a component of my geometry a magnetic field via "amperes law and current conservation"->"remanent flux density
(1 Tesla)" i get 2 annoying cases:

1) the magnetic field interacts somehow with the electric field and i get totally strange fliedlines...how comes that the magnetic field is affected by the electrical field but the electrical field remains unchanged...

2) i deactivate the electric fields and then the magnetic field is just what i wanted "realistic fieldlines", but when i try to give the streamile graph a color expression it just shows 0 Tesla for every line...even though the lines have the right shape.

when i use the magnetic fields no currents module to create the fields the same way the streamline graph works fine...but i need both magnetic and electrical fields for particle tracing ... and it is appearently impossible to combine the mfnc module with the electrostatic module as source for the particle tracing forces SO ANNOYING
