Unrolling a cylindrical surface for post-processing

Bin · October 7, 2015, 22:36

Hi,

I read a star-ccm+ powerpoint recently regarding the post-processing ability of star-ccm+. In one particular slide, it shows that it is possible to unroll a cylindrical surface into a flat surface for post-processing (the image cropped from the slide is attached).

I have checked the setup available in star-ccm+, but I can't find any clue about this. I have also tried to look for further information from the web, unfortunately I get nothing, yet.

Anyone has an idea on how to do this?

Regards,
Bin

*Edit* I found the solution.

Look at the m' theta warp derived part.

Yup, I found that after I created this thread. But I'm striked with another problem now. The unrolled surface is about many times larger than the original dimension, is it always like this? Still figuring how to solve it.
