<p>Hi,</p>
<p>I am coupling the Navier-Stokes and Darcy equations using the
NekNek framework. Everything is working fine in 2D. However, any
3D example in neknek is stuck endlessly in the following line</p>
<pre class="m_-3254427664694514404fragment">call <a class="m_-3254427664694514404code" href="http://www.mcs.anl.gov/research/projects/nek5/docs/html/mpi__dummy_8f.html#af98c20c7332635506f852083f7ee504a" target="_blank">mpi_send</a>(jsend,len,mpi_byte,<a class="m_-3254427664694514404code" href="http://www.mcs.anl.gov/research/projects/nek5/docs/html/findpts__test_8c.html#a37e2ea357c25dfa93b154d03c233cd23" target="_blank">id</a><wbr>,100+nid, intercomm,ierr)
</pre>
<p>within the "intpts_locate" subroutine in multimesh.f. When I
modify the eddy_neknek test case given in the example folder, the
behavior is the same, so the issue is not specific to my examples.
I already checked that the problem is not the memory or the length
of the data processed in MPI_send. Did anyone experience the same
before?<br>
</p>
<p>Thank you very much,<br>
</p>
<p>Best regards,</p>
