I think it can be done using Python programmable filter, but I don't know how to iterate over the time steps...
In paraFoam with the filter "" Calculator" yuo can create new derived quantities.

Yes, but using Calculator filter I will get a value for only one time step.
For example, if I need to compute average WSS, I need somehow to sum WSS values from all time steps and divide it by number of time steps.
With a Calculator filter I think it is impossible...
Calculate the value for each timestep. export it to a txt file and then elaborate it for example with Matlab ore Scilab.
Yes, you are right. It can be done in this way.
But now, the problem is: how to transfer these values back to ParaView to visualize the data...
Dear colleague ,
I think that you can visualise the data in Matlab , Matlab is not bad in that .
Does anybody know hot to compute Wall Shear Stress (WSS) from velocity field using ParaView? Viscosity value is known.
