Hi,
Are you sure the settings in Fluent are the same? For example double precision vs. single precision? (I've had that recently!) Marion. |

Do you mean that there is a difference when you do the POST-PROCESSING of the Fluent-calculation in Fluent directly and in the CFX-like result component in the workbench?
Now that would be a serious issue, although it is not surprising. If you mean that the results are different when tha SIMULATION is conducted in Fluent and in CFX, this is nothing to worry about. |
