Some mesh parameters are related by mathematical expressions. It means, if you modify one of them, the others will be recalculated. In this way, the prism layers parameters can be recalculated indirectly. This option allows the user to select which parameter will be fixed for indirect calculations.

Prism-layers growth control

•Fix ratio: height ratio remains constant if other parameters are changed

•Fix initial height: initial height remains constant if other parameters are changed
