openFoam cell center or node center?

xiyuqiu · January 31, 2012, 02:05

Hello all,

I generated a flow field from OpenFoam and is able to convert to VTK and look at it in paraFoam. However, there is a problem with node or cell center data. I checked the results in foam format. It shows volVectorfield for U. And it looks like cell centered valuse since the number of vectors matches the number of cells. Is this correct?

best,

sam

OpenFOAM uses cell-centered values. Paraview usually interpolates vector data to the cell corners when displaying them as glyphs.
