When running a mesh deformation case in CFX-10, the following warning appears:
+--------------------------------------------------------------------+
| ****** Notice ****** |
| |
| The Second Order Backward Euler transient scheme is not supported |
| for the continuity equation in domains with mesh deformation. |
| This simulation will continue using a First Order scheme for the |
| continuity equation in the domain: |

+--------------------------------------------------------------------+
Can continuity be forced to high Res?

The reason for reverting to first order is that the mass inside a closed system is not being conserved when running second order. It is recommended that you use first order as you will conserve mass with very little influence on the results. With the release of CFX-11 you will be able to run with mesh deformation and second order continuity with 100% conservation. |
