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 .
