Viscous forces in paraview
 

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,

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).
