Meshing a fluid domain involves discretization of the domain into discrete cells. Various meshing techniques are used to discretize a complex model with good quality mesh, which enables the solver to solve the problem without convergence issues. 

The 3DEXPERIENCE platform provides a lot of capabilities that help to mesh different fluid scenario domains, for example from simple to complex. There are certain best practices that the user needs to follow when handling fluid domain meshing. This document mainly focuses on these best practices. The SIMULIA Fluid Model Creation app is mainly used for fluid domain definition and domain mesh creation. 

Prerequisites: The user must undergo SIMULIA Fluid Model Creation training before following this document. 

Target Audience: Simulation Analyst and Fluid Simulation Engineer.

In this best practice, you will learn about:

• Best practices to follow for fluid domain meshing
• Significance of various Hex-Dominant Meshing options
• Troubleshooting known issues with fluids meshing
• Associating different kinds of meshes without using Fluid Domain definition
