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.

Hi,
I am trying to understand the session file "PPF_R15000_3D_VCS.xml." I have two confusion: 1) Since modeType is HalfMode than why "HomModesZ" is set to 2. I think this should be 1.
2) Since the base flow is 2D2C, then is it necessary to include variable "w" in the base flow?
In general, can we use a base flow generated from DNS which only have variables (uvp) in the session file having FIELDS = (uvwp)?
I would be highly thankful for the comments on this issue.
With regards Abhishek Kumar
