data_in_material_coord with cylindrical coord system

[AlejandroStewart]

Hello, I have noticed that the rutine to transform op2 results from elements coordinate system to material coordinate systems gives wrong results when MCID is a cylindrical CSYS.

I have done some research and apparently the r axis is treated as if it was an x axis in a rectangular.

I have attached a little model in which it can be seen by comparing f06 with omid and f06 fom pynastran with and without material axis transformation.

I can't download them. Chrome is giving me an error.

Maybe bigger picture, that functionality was added not too long ago specifically for rectangular coordinate systems. Cylindrical coordinate systems were never considered.

Oh, good to know. It works great for rectangular, super useful.

I'll try to implement cylindrical sys and if it works I'll share it.

Thank you.
