Gmsh+SimpleFoam issue
Hi, I'm sorry for my bad English.

I'm new in this forum and with OpenFoam, and I'm trying to run with simpleFoam the flux of water in an elbow. For that I've made the mesh with Gmsh and exported to Foam with gmshToFoam command.

Checking several discussions in this blog I formulated the different support archives, but when I try to run it, I just got few time's evaluations and I notice that the values of U, p, k, epsilon increases rapidly without a convergence.

I tried changing the mesh dimensions, changing time interval, and other different options but the result is the same: DIVERGENCY!!!

I appreciate if any of you can help me giving me a light with the reason of this problem, cause I'm a kind of desperate with this issue because I need this for my graduation. :confused:

This is the error message that I got on the 6th iteration:
