In addition to the constants in fem.const, you can define constants using the
Const property, see assemble.
If the solver fails to find a complete solution, it returns a partial solution if the
property Stop is on (this is the default).
You can use the property Symmetric to tell the solver that the model is symmetric
or you can use the automatic feature to find out. The symmetry detection tolerance
Symmtol is used for this automatic feature (see “Which Problems are Symmetric”
on page 373 in the COMSOL Multiphysics User’s Guide). If the model is
Hermitian, you should set both the Symmetric and Conjugate properties to on.
