The MultiZone mesh method provides automatic decomposition of geometry into mapped (structured/sweepable) regions and free (unstructured) regions. It automatically generates a pure hexahedral mesh where possible and then fills the more difficult to capture regions with unstructured mesh. The MultiZone mesh method and the Sweep mesh method operate similarly; however, MultiZone has capabilities that make it more suitable for a class of problems for which the Sweep method would not work without extensive geometry decomposition.
In this tutorial of a centrifugal pump you will find the basic setup using Ansys Fluent, we will use the pseudo timestep to accelerate the convergence
Inflation Option The Inflation Option settings determine the heights of the inflation layers. The following options are available: Smooth Transition – This is the default. The Smooth Transition option uses the local tetrahedral element size to…
