X- momentum divergence in 2D axisymmetric model

Hey to all experts out there,
I'm simulating an axisymmetric 2D-model for a rotary kiln. The 3D-model has worked properly, however in order to reduce the calculation effort I want to also build a 2D-model. I have defined it as an axisymmetric model in fluent and have also built my model on the XY-plane along the x-axis, which is the standard symmetry-axis if I got that right. Here comes my problem: Whenever I start the simulation I get the following message after one Iteration: Error: Divergence detected in AMG solver: x-momentum Error Object: #f I have already done some Internet research, but nothing so far could fix my problem. Thanks to everyone who can contribute to this problem, hjan |

I'm not sure if this may cause a divergence error, but is your symmetry axis exactly on the x-axis? if it is off by just a little bit, axisymmetric calculation will give an error. I'm just not sure at what point.

Thanks for the reply, first of all.
I checked my mesh and it said my geometry starts exactly at y=0. I also built another geometry, and had the same problem again, so I guess that was not the problem :/ |
