Hi Foamers,
I am doing simulations on 2D rectangular channel by using steady state solver. I prepared my solver by modifying "simpleFoam" solver. The dimensions (length*breadth) of the channel are 0.143*0.0017 (m). My geometry has 500*10 grids in x- and y- directions respectively. When i run my solver with 500*10 grids, it is giving good results. But when I refine grids (say 600*15) or increase the dimensions of the channel, after running few iterations it is giving the following error.

Error:

Floating point exception

The geometry pass the checkMesh test. Could someone please help me to understand the reason for the error. Thanks in advance.
