Bias and Bias Factor
 
What is Bias factor in Ansys Meshing? How it is computed and applied?

Any comparison to bunching law in ICEM?

How to copy distribution to parallel edges in Ansys meshing?

Please help?

This is a bit similar to bunching law in ICEM but with only four options. You need to specify settings as below

The mesh generated would look like below;

Thanks for your reply.

I know it how to apply but I need its computation in a sense to adjust spacing on two adjacent edges.

If I specify 100 divisions to an edge with bias factor of 10 and the adjacent edge to same divisions and bias factor the spacing is different, keeping in mind that both the edges have different lengths.

How to do so?

Ali,

it would be more specific if you can send screen print of your problem.
By the way did you try "Element size" instead of number of divisions?

1. make transition as "SLOW"
2. Use a growth rate of "1.1"

There is no transition tab in the panel, what to do?

Similar problem i had also in generating the mesh around the airfoil.
