CFX-Post under 5 micron

May 8, 2002, 09:37

Hi all!

We've experienced an intresting and prety error. The CFX Post can not display elements has edges under about 5 microns. I solved a problem in which there was a mesh control of less than 5 micron. In this region I can not display the results.

What can I do to solve this problem?

Just as an idea for a workaround, you might try to create a coarser grid just for display purposes and interpolate the fine-grid results onto that (this is of course not satisfactory if you are interested in flow details in the 5 micron scale).

I calculate a very high Reynolds-number flow of about 0,02 mm thick turbulent boundary layer. So I use inflation, in which the thinest layer is less than 10 micron thick. And I can not display it. I think some kind of tolerance value should be reset. How can I do it?
