cfx solution to Plot3d

Thanitha · February 5, 2015, 00:46

Hi
I want to create a plot3d file from the CFD results of ansys CFX. There is a converter to do this called CGNSViewer. but I need a STRUCTURED Solution file. I tried exporting CGNS files but they are Unstructured. Is there a way to get a Structured solution file from cfx? Any other suggestions are welcome too.

Thank you

No. CFX is an unstructured solver so if you give it a structured mesh it ignores it and treats it as unstructured. So the post processor never sees the mesh structure, so it cannot be exported as structured.

My only suggestion is to export the data from CFX and read it into something you write yourself (in matlab or python or something) which regenerates the mesh structure. Obviously there is quite a bit of programming in this approach.

Hi
Thanks for clearing that out of the way. I'm working on the programming approach. I really think someone should have needed to do it before me. Thanks again.
