- the typical workflow is to change e.g. a constraint setting or material property and to check how and if this change changes the simulation result. it is therefore very annoying that on every call of a task panel the results are hidden.
This PR changes this to hide only meshes and the filter functions but to keep the results. If a user don't like to see results for example to select faces, he hides results anyway.
- uses the constraint for 2D magnetodynamics to perform e.g. Elmer's tutorial non. 15
- modify the Material manager to get rid of magnetization but keep the vectorial functionality because in future there will be support for e.g. birefringence materials etc.
- for harmonically driven forces, the results of course also have an imaginary part. Elmer outputs the real and the imaginary parts as separate result field. However, for several applications one needs the absolute (sqrt(Re^2+Im^2)
- therefore offer also absolute field if there are real/imaginary results
- for electromagnetics we have vector fields and thus need to specify components
- as first step use the new material "Magnetization"
- also get rid of annoying debug messages output on normal use in the material dialog
- is not feasible for practical usage and (was up to now not used, thus no consequence)
moreover, Oersted is a cgs unit while we use SI units, thus also not suitable for FEM, only makes problems for magnetization
- the elctricforce equation is actually a postprocessor and thus should not be first in the list, but after the electrostatics equation (where it belongs to technically)
- also change menu name to be consistent with the other FEM menus
- output only a reasonable number of digits for vacuum permittivity
- output the FC label of potential constraints as comment (helps a lot when having several constraints)
- the writer.py is to large to keep the overview, thus sort out the handling of the different equations (also since more equations will be added)
- This PR sorts out the electrostatic equation handling as first step (more equations will follow once this is merged)
