BL truncation doesn't support 2nd order elements

I get the error "BL truncation doesn't support 2nd order elems. (no error highlighted) Meshing faild" when i try to make boundary layers on an 2D tetra mesh.

Where can i change the setting to "smooth BL" in the HW version 2022.3 ?
In an older version of HW, there is a button in the mesh panel, but in the version 2022.3 i didn't find it.

Thanks for your help!

Apologies that this went unanswered for a long time

Could you elaborate if you are using the legacy HyperWorks 2022.3 (like the one in screenshot below)? Or are you talking about the new interface of HyperWorks? Please send a screenshot.

In the legacy version, it is available as shown below.

Also are you trying to use 2nd order elements for surface mesh? We support only first order elements for most CFD meshing operations, as the solver AcuSolve also supports first order.

I know, that the smooth BL setting is available in the legacy version of hyperworks. But where can i find it in the new interface of HyperWorks?

I would recommend using HyperMesh CFD 2024 (or 2023) for CFD meshing.
In v2022 it was called HyperWorks CFD.

This is CFD specific meshing tool and the one that you showed, is meant primarily for structural preprocessing.

Screenshot below shows the option as "squeeze", the equivalent of "smooth". Hope this helps.
