I found the pressure values in the flow around a cylinder using Computational Fluid Dynamics (specifically OpenFoam). I am trying to extract the pressures on the cylinder surface for Finite Element Analysis.
Flow field pressure
cylinder surface (.vtk mesh)
cylinder overlaps with the edge of the flow field
I tried using SPH database interpolation to find the pressure values at the nodes of the cylinder surface mesh.
- Select the pressure field
- Add the SPH Dataset Interpolator
- In the dialog that pops up, leave the Input to the selected pressure field
- click on the Source bullet, and choose the .vtk mesh
- Click OK and apply
However, the interpolation only occurs at a few points:
Increasing the spatial step causes even those points to disappear. Decreasing the spatial step causes most of the points to disappear. I am not sure what else to try.
