Good afternoon

Does someone know, whether there is a solver for steady-state, incompressible, laminar flow, like simpleFoam without turbulence or icoFoam in steady state?
I'm just starting with OpenFOAM and as a part of a larger project I need to have that kind of solver.
I ask because, even if I know that I can use simpleFoam and turn off the turbulence, is not what I really need.

Thanks in advance.

Any NSE flow solver, including compressible ones (why?), should serve to solve laminar flows at low mach numbers

Yes, you're completely right, all of them are useful, but this is a part of a larger development, where after I will have to implement a brinkman penalization (like in porosity models) in orden to be able then to perform some topology optimization developments.
I know that there is a solver called adjointShapeOptimizationFoam, but its formulation is not the same than the one I one to implement, that is the reason why I have to create something different and adapted.

So, Why SIMPLE does not serve your needs? What does a method for representing BCs (or solids) have to do with your fluid solver?

Because is turbulent, and I need an steady-state incompressible laminar flow solver, to which after I will add a porosity term to implement it in a topology optimization frame

What should that be be? A solver implements the Navier stokes equations, perhaps with some additions. The additionss play the most important role if you don't resolve the time and spatial scales. If you resolve them, they are useless or their coefficients come to (near) zero.

Which other simplification do you need to have? Do you want to have a simpler formulation of the flux problem aside of NS?

There is no assumption in SIMPLE algorithm that forces the flow to be turbulent, or renders it useless for laminar flows. I repeat what I said in my first post: any algorithm (compressible or not) WILL give you incompressible laminar solutions.

How about using simpleFoam and setting

simulationType  laminar;

in your turbulenceProperties dictionary?

finally I was able to create my own solver, without turbulence (and not just de-activating it)

@palarcon could you please share the steady state icoFoam solver
