Hi.
I haver recently installed the foam-extend-4.0 to perform a fsi analysis. I have run a simulation of a liquid flowing over a flat plate with constant speed using the 3dtube tutorial. I have modeled 2 bodies, the blue one is called agua (liquid) its dimensions are 1m x 0.2m x 0.002 m, and the orange one is called niquel (solid) with dimensions 1m x 0.2 m x 0.001 m. The liquid boundaries are as follow: - Inlet (0.2m x 0.002m) - Outlet (0.2m x 0.002m) - agua (region in contact with the solid, face-zone name is agua-zone) - pared-agua (the rest of the walls). The solid boundaries are as follow: - niquel (region in contact with the fluid, face-zone name is niquel-zone) - niquel externo (top face of the solid) - pared-fija (the side walls of the solid). I'm using weakFsiFoam as a solver (fsiFoam solver also works, but is way too slow). The results show that the maximum displacement is below 1e-8 meters, which can't be right. The pressure in the fluid domain is too low (below 10 Pa, but I'm not 100% sure if the pressure shown is not in fact P/rho). I'm also not sure what DD and pointDD files which can be found in some tutorials are for. And last, I can see that in every time step a new polymesh is generated for region fluid, but I can't find a polymesh generated for the solid. Is there any file with the new solid mesh generated, or I should use the pointD file generated and modify manually the solid mesh? I have attached my case. The blockMesh file is in the constant/polyMesh folder and the facezones file is in the fluid or solid folder. Any help or advice you can provide me will be appreciated. |
