Hi all, I'm new in using Op
I'm new in using OpenFOAM and I have a little question to you all, hopefully anyone could give me the right answer.
Why OpenFOAM stores the solution of the field in time directories even if the problem is steady? It is becuse it uses a time-marching approach?
Thanks in adance for your help
For steady state solvers chang
For steady state solvers changing the time step will have absolutely no effect on the solution. It will only change the output directory names. There is no time-marching approach in the steady solvers to my knowledge. Think of each 'Time' instance as one iteration. Maybe someone else can confirm this.
So to answer your question (Why OpenFOAM stores the solution of the field in time directories even if the problem is steady?), I think the reason for the same is consistency between both transient and steady solvers so that tools like foamLog can expect the same format when extracting data from log files. That is just one reason I could think off the top of my head. Rest assured, you can always play with the under-relaxation factors when using SIMPLE by tuning them in one of the dictionary files.
