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.

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

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.
