Process Overview

Fluid-Structure Interaction (FSI) simulation is a complex process that bridges fluid dynamics and structural mechanics to predict how structures respond to fluid flows. The initial step in conducting an FSI simulation involves defining the fluid and structure domains clearly. This phase is critical as it lays the groundwork for the entire simulation, determining how the fluid and solid interact with each other.

Once the domains are defined, the next step is meshing. Meshing subdivides the simulation domain into smaller, manageable parts, allowing for more precise calculations. It’s essential to ensure that the mesh is fine enough to capture details of the flow and structural responses but not so fine that it makes the computation impractical.

Setting boundary conditions is another crucial step. These conditions dictate how the model behaves at its boundaries, influencing the accuracy of the simulation. For instance, boundary conditions can specify velocity inlets, pressure outlets, or no-slip walls in fluid domains and fixed supports or loads in structural domains.

The final step involves post-processing and analyzing simulation results. This phase is where engineers examine the data to understand the behavior of the system under study. They look for stress distributions, deformation patterns, and fluid flow characteristics to evaluate performance and identify potential issues.
