ajithjec New Member AJITH Join Date: Jan 2013 Posts: 10 Rep Power: 13	In 2D Model, Reaction in porous Zone, Error occurs on hooking UDF , DEFINE_VR_RATE in Fluent, The error spikes just after running calculation, 1st iteration itself. Divergence detected in AMG Solver:TEMPERATURE Divergence detected in AMG solver species 0 and Divergence detected in AMG solver species 1...2..3..4 Floating point exception error object #f Any solution for this, Anyone come across such a situation in using UDF in FLuent?
