libra New Member Melika Join Date: Feb 2012 Location: Japan Posts: 24 Rep Power: 14	Hi everyone I am simulating the water flow in a pipe using LES with OpenFoam version 1.6. It seems that there is something wrong with "courant number" in my computations. During the computations it gets bigger and bigger and finally the computation stops. The value I should choose for courant number is 5*10^-4 according to the calculations, but I have even chosen a smaller value: 10^-5. I am wondering why this number gets so big?????
