Hi, How is it possible to calculate the viscouse forces of an OpenFoam simulation in paraview?
In Openfoam I can obtain the sum of pressure forces and viscous forces with the libforces utility.

In paraview I obtain the pressure forces using the following filters:
extractSurfaces
generateSurfaceNormals
calculator (p-pref)*normals
integrate variables

However how can I calclulate the sum of viscous forces in paraview?
Thanks,
WhiteW

Hi,

If you run the wallShearStress utility prior to opening ParaView you can just integrate the wallShearStress vector. There may be a *(-1) required to get the correct direction (I remember this from a couple of years ago, things may have changed).

Regards,
Tom
