Hi all
After meshing the geometry in gmsh and importing it to openFoam for a particular problem, I am getting a floating point error post using icoFoam solver

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?

Floating point exception (core dumped)

The problem geometry and description images are attached. It is a 2d geometry, there are two inlets, one outlet and the rest are walls. Since OpenFOAM by default only works with 3D mesh elements, I performed 3d meshing in gmsh software and imported it to OpenFoam. I checked the mesh on OpenFoam and there was no error. However when I changed the boundaries in boundary file in polyMesh folder generated by gmsh and accordingly changed the initial conditions in 0 folder, i got a floating point error after using icoFoam solver.
Im unable to resolve that error and produce results in ParaView.
I am currently using openfoam version 3.0.0 , gmsh version 2.13.2 and paraview version 4.4.0 all on Ubuntu 14.04 32 bit OS
I am sending the link of the problem description along with the code files. The system and 0 folders were taken from channel folder in icoFoam folder in OpenFoam.

Can u figure out the error and explain it to me.
