Dear All,

I've tried spherigon patches both with meshes consisting of prism+tetra elements and only tetra elements. In both of them it worked and gave me curved edges. However, there are two issues that I want to mention:

1) When I wrote the command below to use spherigon patches

./MeshConvert -m spherigon:surf=7 -m spherigon:surf=8 -m spherigon:surf=9 V_F_Mesh2.xml V_F_Mesh2_spherigon.xml

I got such a message:

WARNING: Spherigon surfaces have not been defined -- ignoring smoothing.

2) When I want to get paraview file to check the mesh by writing

./XmlToVtk V_F_Mesh2_spherigon.xml V_F_Mesh2_spherigon.vtu

I got such a message for a few elements:

Warning: Level 0 assertion violation
3D deformed Jacobian not positive (element ID = 5723) (first vertex ID = 1409)

But I don't get this message when I convert the original .xml file to paraview file (V_F_Mesh2.xml --> the one before using spherigon patches).

I think this issue may lead to problems in my analyses. How can I overcome this problem?

Thanks...

Best Regards,
Kamil

Dear All,

I found such a way to generate my meshes to use in Nektar++:

1) First I create my mesh in ICEM CFD.
2) Then I export that mesh from ICEM CFD as a Nastran file (with *.dat extension).
3) After that I open that *.dat file in Gmsh and save it as a *.msh file.
4) Finally I generate my *.xml file from that *.msh file.

This works in Nektar++ but I have a problem about generating curved edges in ICEM CFD. There is no such option or I couldn't find how to succeed this. Is there any one who use this method to generate mesh for Nektar or can inform me about generating high order edge in ICEM CFD?

NOTE: I've tried to generate curved edge in Gmsh with the imported *.dat file but it didn't work.
