Dear All,
I am simulating the dispersion of chemical substance in the atmosphere using FLUENT. I defined the wind profile at inlet include velocity, temperature, k, epsilon through UDF. Firstly I run with steady to got the full wind profile. Then I run with transient to simulate the dispersion of chemical substance. However I got a error message " Error: Divergence detected in AMG solver: epsilon ". Do anybody know how to solve it? Please tell me. Thank you
