i am using ANSYS 12
i have a problam in meshing
i am using patch independent tetra mesh.
sir i want some simple formula or procedure for calculate

Min Size = minimum gap size / 5...10
Max Size = maximum gap size / 10
With that values you have at least 5 to 10 elements in your smallest gap and at least 10 elements in the largest gap. Take this as an first assamption and find values that are reasonable for your project.

I agree with Max E.'s suggestion as a good way to start.
However, it is very model and situation dependent (no one size fits all). Also, you could have a global min size and a smaller local min size...
You will probably need to come up with your own rule-of-thumb based on your own specific needs.
