In CFD simulation does the geometry meshing affect the solution.

Mudassir khan

There are different options available for meshing the geometry. How to decide which type of meshing is good for a particular problem. Is volume meshing sufficient for CFD simulation or does geometry meshing influences the result. Hello experts I am trying to simulate the Dambreak simulation in open channel geometry. I Have a few doubts for creating my model. 

1.How to verify the units of meshing once the Spline geomtery in converted to FE geometry. Further surface or solid meshing is necessary to run the CFD simulation?

Is the volume meshing not sufficent for CFD simulation why?

How to define the material of solid and fluid inside it, Beacuse when i assign material it take all the solid that we have?

Best to refer to the dam break tutorial - ACU-T: 4000 Dam Break Simulation.

You'll need a volume mesh - and the outer 'faces' of the volume(s) on which to define the boundary conditions.  You have mesh controls (sizing, etc) on both the volume and the surfaces.
