Hi guys
I defined a macro for density, viscosity and conductivity for a flow by udf.when I start the run I received some errors. what these errors means? '' Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature Divergence detected in AMG solver: x-momentum Divergence detected in AMG solver: y-momentum Divergence detected in AMG solver: z-momentum Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature Divergence detected in AMG solver: x-momentum Divergence detected in AMG solver: y-momentum Divergence detected in AMG solver: z-momentum Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature Error at host: floating point exception Error at Node 0: floating point exception Error at Node 1: floating point exception Error at Node 2: floating point exception Error at Node 3: floating point exception Error: floating point exception Error Object: #f "" thanks |

It means that your simulation had extremely big problems to calculate the next iteration.
Probably you made one of the inputs much too large or much too small. |
