grid
 

Hello frns,

I want your help, i want to mesh a geomotery with first cell distance of the order of sub microne (for hypersonic flow computations). I know the options to do so. But in gambit it shows a warning that i am exceeing geomoteric tolerence limit and ** it will create negative volume while going to sub microne levels. On other hand i can write a simple program to do so. please help me, how to do this in gambit.

Thanks in advance

Maybe you should consider to make the cells a factor 1000 bigger. Then scale the mesh later in Fluent. You can just do a simple test to see if it works.
