Need help with my dissertation

ltiago94 · March 21, 2018, 06:25

Hello everyone, I'm new to CFD and OpenFoam in particular. My dissertation theme is to model a block for coast protection that someone already had tested in laboratory.
I intend to recreate the experiments but using OpenFoam and numerical modelling to validate the results and maybe improve the structure. I had already written some files and did some tutorials but now I'm stuck in a point I can't leave and that's not good for my project.

I'm having trouble with defining some settings for the problem to run in openfoam, for example, to define a geometry for the block to be removed from the mesh and proceed with the analysis.

My main problems are with the setFieldsDict, because I need to define a depth of the channel filled with water but the other part is air.
Also, I don't know how to define the geometry for the block (simple one to start) and to include it in the entire process.

If anyone could help me I'd be really grateful.
Thanks,
Tiago

I have several ideas that you can try with geometry. We can discuss.
Thanks,
