Rose Guest Posts: n/a	Hi, This is a divergence issue. I get the following message in FLUENT: "divergence detected in AMG solver: temperature" I am running a 2D symmetrical airfoil with a moving surface (wall with momentum) condition on just a portion of the leading edge. Is there a general way to deal with these type of divergence errors? Do you think it may have to do with my grid? I get this error at higher surface speeds (>= 1 and 2 times the freestream velocity). The flow is Mach 0.2, Re ~ 10^7. Any suggestion would be appreciated. Rose
