Hello,

I'm facing problem in converting .stl file to .ftr format using surfaceConvert 2.stl 2.ftr
Reason for conversion : refineImmersedBoundaryMesh need .ftr file to refine the mesh.(If you can tell me a way where I don't need the ftr file that will also do)

Error :
Segmentation fault (core dumped)

At the time of compiling the fe40 for every other utility the results were shown as name_of_the_library is up to date
but for only surfaceConvert I got this message

g++ -m64 -Dlinux64 -DWM_DP -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3 -DNoRepository -ftemplate-depth-200 -I/home/environ/foam/foam-extend-4.0/src/meshTools/lnInclude -IlnInclude -I. -I/home/environ/foam/foam-extend-4.0/src/foam/lnInclude -I/home/environ/foam/foam-extend-4.0/src/OSspecific/POSIX/lnInclude -fPIC -Xlinker --add-needed -Xlinker --no-as-needed Make/linux64GccDPOpt/surfaceConvert.o -L/home/environ/foam/foam-extend-4.0/lib/linux64GccDPOpt \
-lmeshTools -lfoam -ldl -lrt -lm -o /home/environ/foam/foam-extend-4.0/applications/bin/linux64GccDPOpt/surfaceConvert

Please try to reply asap as this is important for my project.

Hello,

foam-extend 3.2 gives me same issue on Ubuntu 16.04 LTS. I succeeded 1 year ago on a different machine/OS with same configuration today. It is too weird.

emre@acer:~/FOAM_RUN/2cylinders/constant/triSurface$ surfaceConvert ibCylinder2.stl ibCylinder2.ftr

This is frustrating. I also tried this issue in foam-extend 4.0 on Ubuntu 18.04. I encounter same problem:

I'm facing the same issue with fe40. Anyone found the solution to this?
I'm trying to follow an immersed boundary tutorial, so not really sure of how this ftr file is utilised. Is there any way to overcome this or just use stl instead?
