[Nek5000-users] Nek5000-users Digest, Vol 92, Issue 2

[nek5000-users at lists.mcs.anl.gov]

Hi all,

Sorry for the confusion in the first post. Any 3D Neknek simulation is  
stuck endlessly in the following line

call mpi_send(jsend,len,mpi_byte,id,100+nid, intercomm,ierr)

within "intpts_locate" subroutine in multimesh.f.

Could anyone please share if you have experienced similar issues, and  
how can this be resolved?
Thank you very much,

Best regards,
Sudhakar
