Why won't my circuit coupled Magnetic Vector Potential input
converge in ANSYS 8.0?
The default convergence criteria are not appropriate for
a circuit coupled analysis. Since the magnetic solution is the
only nonlinear one, you can replace the default convergence
criteria with CNVTOL,CSG and the input will work.
NOTE: It is not recommended to use permeable and
non-permeable material together with SOLID97 (See assumptions
and restrictions.) It may be acceptable in this case in which the iron
forms a complete magnetic circuit.
