There is a post of Tobi's eq-code explanation on viscous stress.

In incompressible flow, beside normal stress (taken out as p*I), the viscous part is only a function of deviate part of grad(U) (or its transpose).

In "SymmTensorI.H"
there are tow functions for deviate part of a tensor as explained by Tobi : dev and dev2

  • Use Plot3D format to design the mesh, then convert with datToFoam and then run blockMesh.
  • Use OpenFOAM's codeStream and code it directly

Well, since you're building your own code, I suggest that you study this wiki page: http://openfoamwiki.net/index.php/HowTo_debugging

As for the output you're getting:
  1. Line #1 is telling you that a SIGFPE has been triggered: http://en.wikipedia.org/wiki/SIGFPE#SIGFPE
  2. Line #3 is telling you more or less where the problem occurred.
Best regards,
