Hello at all,
I'm new in combustion simulation with openfoam. I started to define my own geometry/case with gmsh and the set up I have done similar to the "counterFlowFlame2D" example. So when I start the solver I got a floating point exception at the beginning (after the "Selecting thermodynamics package" step). I'm not sure where to find the error. May be here is someone who can give me some advises. If necessary I would share my testcase. Here you can find it: http://www.sendspace.com/file/fza8aw Thanks in advance and best regards pajofego Code:
