In fluid-structure interaction analysis, fluid simulation is a crucial aspect. The following details how to perform fluid simulation modeling and processing within the Hypermesh software.

- Fundamental Principles of Fluid Simulation

In fluid mechanics, the motion of fluids can be described using assumptions of continuous media and Navier-Stokes equations. The fundamental principle of fluid simulation involves solving for parameters such as fluid velocity and pressure through numerical computation methods to simulate the motion state of fluids in space.

- Steps for Fluid Simulation Modeling in Hypermesh

1. Import fluid model: Import the geometric model to be simulated into Hypermesh, which can be in .step, .igs, or other CAD file formats.
2. Divide fluid elements: Partition appropriate fluid elements on the model based on the requirements of the fluid simulation, such as triangles, quadrilaterals, etc.
3. Define boundary conditions: Set the boundary conditions for the fluid model, such as inlet velocity, outlet pressure, and other parameters.
4. Set fluid materials: Based on actual conditions, define fluid properties such as density and dynamic viscosity.
