[General] Convert from Cartesian to Cylindrical

crashmaker · June 10, 2015, 12:54

Hello!

I solved StressAnalysis problem on OpenFOAM. I have sigma in Cartesian coordinates and I can see sigma in Paraview. But I want to see sigma in Cylindrical coordinates. How very easy do this? May be there is a function in Paraview which allowed sigam tensor convert from Cartesian coordinates to Cylindrical.

I don't know if there is an existing function/filter in PV to accomplish this. But it's possible to perform tensor transformation. I can think of two ways:
1. Use the "programmable filter" to enter the several lines of code (python script) to perform the transformation. You would hard code the angles. This is a relatively easy approach.
2. Write a filter in C++ to do this. You can enter the angles in the interface. This approach is daunting if you have never done similar things before.
