Hi Abhishek,

Have you tried with setting this value to 1, and did the solver work
and returned the same result?

1. Anyway, as far as I understand what is in
SolverUtils/EquationSystem.cpp the value of HomModesZ is overwritten on
initialization: 2 for SingleMode and 1 for HalfMode - so the value in
the session file would seem redundant (Solver starts with this value
removed).

2. Yes, AFAIK you need to have w in the BaseFlow section. It does not
need to come from a file, you could do sth. like this:

<F VAR="u,v,p" FILE="bflow.fld" />
<E VAR="w" VALUE="0" />

So you can use a 2D solution with Fourier expansion.

Best,
Stan Gepner
