Interpolation of Initial Values error

Neys Schreiner · February 27, 2017, 05:50

Hi guys,

I am running a reasonably large problem (~11m cells) using CFX v17.0, running on a cluster. I can run the problem from an automatically initialised flow field, but when I try a restart from a previous solution I get the following error:

+--------------------------------------------------------------------+

| Interpolation of Initial Values |

+--------------------------------------------------------------------+

<IBM Platform MPI>: : warning, dlopen of libhwloc.so failed /apps/intel/parallel_studio_2016/impi/5.1.3.210/lib/linux_amd64/libhwloc.so: cannot open shared object file: No such file or directory

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| Error interpolating results onto the new mesh: |
| /apps/ansys/v170/CFX/bin/linux-amd64/double-int64-ifort/solver-pc- |
| mpi.exe was interrupted by signal SEGV (11) |
+--------------------------------------------------------------------+

Has anyone seen anything like this before? Any advice would be appreciated.

Regards,
Neys

As found in this thread, the error appears to be linked to the scheduler (SLURM).

This can be solved by adding:

unset SLURM_GTIDS

to the submission script.

Hi,
I faced with that error and the problem was solved by changing the folder in which the initial res file ewas saved. Try to save your files in a shorter drive address.
Hope that works for you too.
