Dear All,

Could you helps for this please,

I got identical problem as below after 3370 iterations in my 3D bluff body cantilevered using UDF

# Divergence detected in AMG solver: x-momentum -> Increasing relaxation sweeps!

# You may try the enhanced divergence recovery with (rpsetvar 'amg/protective-enhanced? #t)

reversed flow in 7250 faces on outflow 6.

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: pressure correction

Error at Node 0: floating point exception

Error at Node 1: floating point exception

I just modify length bluff body from all case including UDF which original case it is running well. In addition, the case without UDF is run well.

I will send original UDF and my modified UDF if it possible.

I am totally a new comer in UDF

Thanks a lot in advance

regards

Barata
