hello,

may i know how can i import gridgen mesh into fluent/gambit? what type of file format must i use to save in gridgen to achieve this?

thank you.

From GridGen you should be able to save a Fluent .cas file.

Goto the Analysis Software menu. Set your flow solver to Fluent. Then use the Export Analysis Data command. It will write a .cas file.

Hope this helps.

ok, got it. but the step i'm missing is actually defining the block. before that is done, the export to analysis data command is greyed ot.

I can't tell from your reply whether you figured out how to create blocks or not. So just in case... Blocks Create Assemble Faces If the grid is structured, select the domains that comprise each of the 6 faces, face by face. If the grid is unstructured, select the domains that comprise the face. If the overall grid is 2D (as set in the ASW menu), you'll make just one face for the structured grid.
