[Nek5000-users] Unstructured Mesh

Hi JP,

Is your mesh made up of fully hexahedral elements (quadrilaterals in 2D)?
 Nek supports unstructured meshes, but only these element types.

If your mesh is fully hexahedral, then my suspicion is something went wrong
with converting the .vtk to the .rea in terms of ordering the nodes for
each element (Nek expects a certain ordering)
