Christoph, Do you want the pressure gradient?
Do you want the velocity gradient? Do you want the energy flux through a cell facet(face)? What is the geometry of your mesh cells? Maybe I can help if I had the information like the above. Sam Key On 1/26/2017 6:09 AM, Christoph Grüninger wrote:
Dear ParaView! I have a simulation computed with a finite volume method which outputs pressure as cell data. The pressure gradient is related to the velocity (Darcy's law). Is it possible to calculate the gradient as a finite difference between the cell centers of adjacent cells? The result would be located between the cells, not sure whether this works at all. Converting cell data to point data and using the gradient filter is not what I want.
