Calculate local Nusselt - Average T in perimeter
 

Hello all

I have flow around a 3D object and I would like to calculate the local Nusselt number.
For this purpose, I need to average the temperature gradient along the perimeter of the object and at each x position.
Does anyone know how to do that? A procedure in ParaView would be the most convenient solution for me. Thanks in advance

im not sure but i guess you may need to program for it and i dont know any easier way, so i suggest you that search for programmable filter or python shell in paraview
