Ansys Fluent Class#4 Let’s do more practice&Focus the Solver

Ansys Space Claim( Creating Model), Ansys Meshing (Meshing Method), Ansys Fluent(Solver)

Ansys Space Claim(Creating Model)= Creating 3D Model from scratch with using tools such as sketch creation,pull, blend,Split body,move, do practice with assembly model, and detailing the drawings.

What you’ll learn

Workshop

Completion of this workshop   will help to gain an understanding of:

•Modes   available in Space-Claim

•The concept   of “Planes”

•Creating   sketches

•The available   modeling tools

•Advanced   features in the Structure Tree

•The display   Tab

 

Ansys Meshing( Meshing Method)=  Learn difference between the Main Meshing method such as Tetrahedral(Patch Conforming and Patch Independent) and Hex Meshing(Sweept, Multizone ,Hex dominant) and learn how to recording the meshing

Workshop

This workshop   will introduce different meshing methods available in ANSYS Meshing

Objectives

Testing and comparing the mesh generated by the different methods:

Automatic (Tet   Patch Conforming)

Multizone

Decomposition   for Sweep Meshes

-Automatic   (Tet & Sweep)

Ansys Fluent(Solver)=how to specify the solver and choose methods and controls, how to initialize the solutions, how to use the report definitions to monitor and judge converge  and talk details in Solving Ribbon such as Method, Controls, residuals, initialization, Calculate section and converge criteria.Doing more practice with Workshop model section.
