The procedure for performing
adaption is as follows:
Yplus/Ystar Adaption panel, select
Ystar as the adaption
Yplus if you are using the enhanced wall treatment.
If you are using wall functions, you can select either type.
Choose the wall zones for which you want boundary cells to be marked or adapted in the
Wall Zones list, and click on
Compute to update the
Max fields. The values displayed are the minimum and maximum values for all wall zones, not just of those selected.
Min Allowed and
Max Allowed. Cells with
Min Allowed will be coarsened or marked for coarsening, and cells with
Max Allowed will be refined or marked for refinement.
If you are using the default hanging node adaption, you will not be able to create a grid that is coarser than the original grid. For this, you must use conformal adaption that is conformal coarsening which is only available for 2D or axisymmetric geometries. See Section
26.12 for details.
Mark to mark the cells for adaption (refinement/coarsening) by placing them in an adaption register (which can be manipulated as described in Section
26.11.1), or click
Adapt to perform the adaption immediately.
To disable refinement or coarsening, or marking for refinement or coarsening, turn off the
Coarsen option before marking or adapting.
