Summary0000803: Segmentation Fault (Core Dump)
DescriptionIn my case, flow enters a pipe in +Y direction and turns at 90 degrees in +X direction. Flow is turbulent and Reynold's number is 3x10e5. Medium is air. When I type simpleFoam, after 50 iterations, terminal gives message "segmentation fault (core dump)". Please advise. I have also tried to change value of inlet and outlet in nut from 0 to 0.0001 but to no avail.
TagsNo tags attached.

What is happening at 50 iterations? E.g. is it trying to write and run in a write-protected directory? Or are functionObjects being run. Can you attach a case?

Many thanks for the swift response. Case is 8MB and could not be attached here. I have uploaded it at the following web-link

http://www.4shared.com/archive/U267rBPa/90mitretar.html

It contains all files. Image is also attached of the terminal showing the message.

Should work now but if it still does not, perhaps you can contact me at sihaqqi@gmail.com from some email address and I can send it to you on that.

 Hi Mattijs,

To avoid wasting your time identifying same solutions, I intend to advise that posted this question at
http://www.cfd-online.com/Forums/openfoam-solving/115251-segmentation-fault-core-dumped.html
and I have tried all things but still errors remain. I need to get powerLawVelocity profile working and not use fixed velocity.

The first line in your write routine goes

powerLawVelocityFvPatchVectorField::write(os);

so it recurses until it runs out of stack. I guess you want to do

fixedValueFvPatchVectorField::write(os);

To find these problems recompile with -DFULLDEBUG -g -O0 in EXE_INC in Make/options and use gdb or ddd on the resulting core file.
