Hi Everyone

I've used newSimpleFoam Solver for laminar duct steady flow.
the geometry is pipe with length and diameter equal to 1 and 0.0125 meter in order.
I generate the mesh as follow with blockMesh:

(150 30 60)

when I run the case the following Error appears in terminal:
Time = 22

smoothSolver:  Solving for Ux, Initial residual = 0.0260254, Final residual = 6.74263e-07, No Iterations 16
smoothSolver:  Solving for Uy, Initial residual = 0.098026, Final residual = 3.93969e-07, No Iterations 18
smoothSolver:  Solving for Uz, Initial residual = 0.0733993, Final residual = 3.43596e-07, No Iterations 18
GAMG:  Solving for p, Initial residual = 0.180537, Final residual = 0.0333237, No Iterations 1000
time step continuity errors : sum local = 0.00686104, global = 0.000504269, cumulative = 0.000742071

Floating point exception (core dumped)
I know the solver which I developed recently is ok because I have run different cases with this solver.

can anybody help?

thanks a lot

I change the quality of Mesh from (150 30 60 ) to (300 20 20) and the problem in my last post is solved.
