Simple grading technique of OpenFOAM
 

Dear All,

Does anyone knows how to relate the simple grading with expansion ratio of 10 (eg. x1,x2,x3 = 10,1,1) along x1 direction with respect to total length ratio?

More specifically, I have to write the mesh characteristics as:

(delta s/S)min

where S = total length, delta s = smallest cell

If I have 2D case with S=1 and total cells along x1 = 40. What will be the value of "(delta s/S)min" for simple grading with expansion of 10.

Thanx in advance! Urgent! :)
