Divergence Detected in x-momentum
 

I am trying to simulate magnetic drug targeting in a curved artery, for a non newtonian flow defined by the modified casson model, and Generalised Pwr Law model.

I am using the DPM model to simulate the Magnetic drug.

After solving the non-Newtonian flow, when I am loading the DPM_BODY_FORCE UDF, and trying to execute that in fluent, I am getting Divergence detected in X-momentum.

Please, suggest, if anyone has something useful.
