This indicates there is some inconsistency in the mesh definitions. Where was the mesh created? (It refers to having at least some hex elements - so maybe not created in AcuConsole.) Did you do mesh checks in that software where the mesh was created?

Thanks for your reply.

Meshing was done in Hypermesh. All the parameters were checked before exporting.

Also at the time of exporting, no error message was displayed.

Will check the meshing again
