Which Solver should I choose?
1 Attachment(s)
Hello,
I would like to simulate incompressible laminar flow over a semiinfinite flat plate at zero incidence, with constant density throughout the flowfield. The thing is that I want to compare the results that I will get with OF, with a homemade algorithm that I have built in FORTRAN, that simply solves the Continuity and XMomentum equations, like listed in the attachment. I am thinking of choosing icoFoam or simpleFoam with turbulence turned off, but I can't understand how they are different (Transient vs Steady State solver) and what will the impact on my obtained solution be. If anybody has a remark, I would be grateful :) Mike 
If you are interested in steady state solution, u can opt for simpleFoam.

So, if I choose simpleFoam, what would be a reasonable value for timeStep in ControlDict? Should I set timeStep= 1 sec and run until convergence?

Yes, and if you want 1D case, create a mesh with only one cell in the Y and Z direction.
Best,

Well, I want to increase Reynolds (~10^7) so that I have turbulent flow. I used kepsilon model. I just introduced 2 files (k and epsilon) under 0 folder and the necessary fvschemes and fvsolution modifications. Is this correct? Or do I need other changes and files under 0 folder, like nutilda ?
And after that, how can I plot the uvelocity in gnuplot or paraview (if possible), towards timesteps ? Thanks! PS: i added 2 images. The first is the laminar fully developed boundary layer and the second is the turbulent fully developed boundary layer. 
mikemech, Alberto....
why would one need to give a time step to this type of problem, when you are doing steadystate simulation??? if you have steadystate the time dependence would disappear wouldn't it??? Thanks Ricardo Quote:
