Beginner in OpenFoam

Hi,

I have just a commenced a PhD in wind resource assessment. In this I will be modelling the flow of a wind over a complex near coastal terrain.

I am completely new to the OpenFOAM world and indeed to any CFD software.

I have completed the tutorials online, but I am stuck as to to the next step I should take.

Could someone please advise on the next step I should take with learning the software?

I am also a beginner and I think the next step would be to create your own geometry and simulate it.

The standard method for learning OpenFOAM is to run the tutorials as written, then start changing things (mesh, boundary conditions, etc). Run all of the incompressible and mesh tutorials (of interest), then figure out how they work. Develop a method to import and mesh terrain files. Then substitute your terrain for what's in the tutorials. Look into inlet velocity profiles, boundary conditions, atmospheric conditions. Investigate buoyancy driven flow modeling, surface roughness, etc. Search the forums for threads of interest. It takes some time to develop competency with OpenFOAM (or any other CFD code) - it's a great tool, but the learning curve is steep.

Happy hunting, Alan
