Hi Dr. Sherwin,

Let me first state that this problem is a different one than the previous straight pipe flow problem. This is a constricted pipe flow problem. In this mesh there is no curved edge (means there is no degenerated edge etc.) . It is just obtained by rotating 360 degree a 2D profile. If you want I can send you screenshots of my mesh.

Regards,
Kamil

HI Kamil,

Can you first confirm whether you mesh is now correct? 

Regards,
Spencer.

Dear All,

When I try to run an analysis by requesting a History File, Nektar++ 4.0 tells me that:

History point 0,0,0 cannot be found in the mesh.

but in the .xml file 0, 0, 0 point exists as vertex as you see below:

 <V ID="9761">0.00000000e+00 0.00000000e+00 0.00000000e+00</V>

When I remove history points part from the .xml file, it runs without problem. What may be the reason for this problem?

NOTE: The mesh is composed of both pyrisms and hexahedras. So .xml file includes two composites.

Regards,
Kamil.
