mpi_gnu_linux_64, FDS+Evac with Segmentation fault #7906

Closed gjaeger closed 4 years ago

gjaeger commented 4 years ago

After compiling FDS (current master version) with GNU Fortran and OpenMPI, I get a segmentation fault when executing evac files (like evac_memory_test0.fds).

My result:

$fds_mpi_gnu_linux_64 evac_memory_test0.fds

The fire simulation (like couch.fds) works.

What's my mistake?

rmcdermo commented 4 years ago

I assume this is not the same zone issue?

Try compiling and running the _db (debug) version. It should give us better traceback and a clue for what is going on.

Yes, it's not the same issue.

drjfloyd commented 4 years ago

Yep that is a bug. Surprised we haven't had that pop up before. DETERMINE_FIXED_ELEMENTS is called from PROC_HVAC but we aren't checking to see if there are any HVAC elements. The Intel compiler really should throw an error for this as well.

drjfloyd commented 4 years ago

Should be fixed now.

gjaeger commented 4 years ago

Thanks. It works.
