I have been trying to generate a combustion mesh for a mexican hat piston with tappered edge,though i was successful but it happens that i had a lot of non-convex cells and cell inversion in my mesh ans its making it impossible for me to continue with my computation.Please can anyone give me a hand on this problem.Anxiously waiting for a reply.

Why not try ES-ICE from CD-adapco

Thank you very much for your contribution.I'm actually experiencing the difficulty (non-convex and inverted cell) using KIVA-3V (K3PREP) mesh generation program.Incase you have any advice towards this i will really be grateful.Thanks again for the response.

If you want to use GAMBIT I can help you.

I wouldn't mind,its just that i am not too familiar with GAMBIT.Also,i dont know if it can work with KIVA-3V main program.Please,enlighten more.Thank you and i wait for your response.

If you are using unstructured version of KIVA then GAMBIT is ok..If this is the case send me drawings of your geometry I will have a look and hope to generate the suitable grid for you.

Thanks alot.Can i have your email address,i will forward the file to you.

Thanks

Hi can any one guide me how to select NBO values. if it greater tahn 0, then how to decide i,j,x,y for all those points
