Mohsen, I just noticed that the problem is not coming from "bl", but from the "projectcad" module. I found out that no matter where I increase the order of the mesh, in Gmsh or NekMesh, if I create a mesh with order=7 I get the same error: Wrong number of modes? I don't believe that the specific order of 7 is the issue and it may be true for higher-order meshes. I also tried to manually change NUMMODES in the xml file but it didn't solve the problem.

Hi Syavash,
Could you send the command you used? Also note that to modify the bl, the mesh should have a closed bl with only one layer of mesh. So if using other software to mesh, set it to produce only a single layer that spans from wall to an extent you wish

Dear All,
After I converted the mesh to xml format with order=7 (using NekMesh), I tried to split the first layer adjacent to a wall using the "bl" module with nq=7. However, I get the following error:
Wrong number of modes?
Is there an incompatibility issue here?
Kind regards syavash
