How to output grids expansion ratio in ICEM
 
Hi,

May I ask how to output grids expansion ratio in ICEM?

I didn't find the 'expansion ratio' option among the grid quality column. Where is it?

Thank you.

Are you talking about volume change ?

Grid expansion ratio is also called grid stretching ratio. It is the ratio of distances between adjacent grid points along a grid line. Thanks. :)

Do you mean Grid expansion rate?

It is with mesh smoothing option.

Yes. It's called Volume Change in ICEM.

I obtained the message 'Minimum quality for "Volume Change": 0.99'. May I ask how is this quality defined? Where could I find the grid quality definitions in ICEM? I didn't find them on the ICEM User Manual.
