cfdOF install

I'll need more information as detailed in the link below.

I've now installed it on two computers - on one machine it works fine, on the other I'm getting issues.

libgomp: Thread creation failed: Resource temporarily unavailable

I haven't seen that before. I can only advise to try to uninstall and re-install blueCFD, and reinstall cfMesh.

Thanks - I've tried that, and in doing so I notice that I get a warning about there already being a version of MPI installed. My guess is that this is somehow related. A quick google on the message brings up some discussion around it being an issue with the number of threads being created.

Is there any way to execute cfmesh on a single thread? I've tried modifying the Allmesh file that's generated as below, but it didn't help in this case

Code: Select all

#!/bin/bash

OMP_NUM_THREADS=1
runCommand()
{
    if [ "$1" == "mpirun" ]; then sol="$4"; else sol="$1"; fi
    sol=$(basename -- "$sol")
    sol="${sol%.*}"
    if [ -f log."$sol" ]; then rm log."$sol"; fi
    "$@" 1> >(tee -a log."$sol") 2> >(tee -a log."$sol" >&2)
    err=$?
    if [ ! $err -eq 0 ]; then exit $err; fi
}

# Extract feature edges
runCommand surfaceFeatureEdges -angle 60 "constant/triSurface/XOR_Geometry.stl" "XOR_Geometry.fms"
runCommand cartesianMesh

if [ ! -z $FOAM_API ] && [ $FOAM_API -ge 1906 ]
then
    runCommand surfaceMeshExtract mesh_outside.stl
else
    runCommand surfaceMeshTriangulate mesh_outside.stl
fi

runCommand surfaceTransformPoints -scale "(1000 1000 1000)" mesh_outside.stl mesh_outside.stl

Changing

Code: Select all

OMP_NUM_THREADS=1

to

Code: Select all

export OMP_NUM_THREADS=1

may do it.

Thanks again. For some reason I need to set export OMP_STACKSIZE=100M. This was defaulting to 1G, which was what was killing it.

No idea why this is happening, I can only guess there is a conflict with something else installed on my machine.

Glad you found a workaround - thanks for reporting back.
