Hey guys,

I have a question about why my solver is crashing on the first subiteration. In my case directory I am running >> fsiFoam (a solver just like simplefoam ... a steady-state solver for incompressible, turbulent flow) , and this is what happens:

It appears that the error is in the libOpenFOAM file, which is a shared library file ... has anyone experience a problem similar to this or know what may be the cause of this issue?
