hi,
I wanted to know what solver to use for steady state incompressible Newtonian flow. Do I run icoFoam to steady state or remove turbulence model from simpleFoam.

Run standard simpleFoam but choose the laminar turbulence model.

Thanks.
Isn't simpleFOAM a steady state solver. Then why does it solve over time. (The solver loop runs from starttime to endTime). Maybe the loop is for something else but I am not able to figure it out.

For simpleFoam and the other steady-state solvers time is simply used as an iteration counter so it is useful to set deltat to 1 but it isn't essential.

simpleFoam is a steady state incompressible flow solver. but there are two tutorial cases (included with OpenFoam package) have initial time 1 and end time 1000 with deltaT =1 mean time varying solutions. It sould have only single time step.

(A bit now to this CFD stuff huh?)

Navier-Stokes equations are non-linear and 1000 is the iteration count.

Got it?

How can we choos the laminar turbulence model
 

Hi.
How can we choos the laminar turbulence model:o

Hi
See dam break tutorial

hi,
What's the relation between damBreak and a incompressible laminar Flow in steady state. I don't understand what's your meaning.
thanks

Hello
What you want has been used in that tutorial. See constant folder. turbulenceProperties file.
Good luck
