i have problem in grid checking of gambit geometry.plz give me some tips so that i identify problem in the grid. fluent do not run the mesh file and show warning like that: Grid check failed Non-positive volumes exist plz inform me quickly

Hi

Check the grid in Gambit first. Right-click on the exclamation mark (!) and choose the "check mark" and see the message provided. perform this on each face/volume to find where exactly the problem is.

I get this message when a zone is not properly meshed. Do you have a highly curved line on a meshed face and not enough nodes on it? check the mesh there.

Good luck

I think its related to your computational axis. all the cells should be right handed. check for this. you can fix it in gridgen or gambit whichever mesh generator u r using
