2D simulation in FlowVision 3.12.02

BRIEF SUMMARY OF THE ARTICLE

1. A two-dimensional formulation simplifies the debugging of a project at the very beginning of modelling a complex process. It is more rational to perform the tasks of verification and solution convergence studies in a 2D formulation. The modelling of some processes doesn't require a 3D simulation at all.
   
   
2. In FlowVision 3.12.02, a new method for setting two-dimensionality has replaced the method with a remote non-calculated subregion. A non-calculated remote subregion was an intermediary technique developed by our engineers. Now there exists a software solution - the "2D direction" option.
   
   
3. When using the 2D direction, you should always use the absolute criterion for small cells, which is set by default (Limiters > Phase Limiters > Small Cells = Absolute).
   
   
4. For flat and sector 2D arrangements, the technique with a non-calculated subregion continues to work. However, we highly recommend that you adapt 2D projects from previous versions to use the "2D direction". This will allow you to get a more stable solution (since the absolute small cells criterion will be used, and not relative, as before), and the overall project will look neater.
