FIDAP V8.5 - Solver interprets problem as linear when nomomentum is specified, causing it to stop after one iteration


In a case with only conduction, if a subroutine boundary condition causes nonlinearity,
fidap will still think that the problem is linear and will stop after one iteration with the
fully coupled solver.
The fully coupled solver can NOT be used. The segregated solver must be used.
The reason for this is that if the fully coupled solver is used and the problem
has the nomomentum keyword, then FIDAP thinks the problem is linear and only
does 1 iteration. In this case, the problem is nonlinear because of the
particular flux boundary condition that is being applied.
