Divergence detected in AMG solver:species-0
 
Hi all,

I am using fluent 12, I am simualting flow in duct which is separated by a membrane and need to findout the mass transfer(concentration gradiant) through the membrane. I am also using compiled UDFs which contains the macros DEFINE_ADJUST, DEFINE_SOURCE. While compling the UDF i dont get any error.
After initialization, when the run started, i got " Divergence detected in AMG solver:species-0". I used F-cycle in the solver-->control.
Can anyone help me to rectify this problem?


Thanks
Arulmurugan
