Acceptable mesh quality???
 
Hi ,
This is my mesh details and i am worried about Exp factor value as document states that it (Range) should be less than 20. I am using Hexdominant mesh for homogeneous multiphase problem including free surface and thermal energy model.
Could any one please tell me if it is acceptable or total failure?? it will save me a lot of time. Thanks
