How to Duplicate the FEM model and Analysis case in Fluid Dynamics Engineer

In the world of engineering simulation, both efficiency and accuracy are essential. The Fluid Dynamics Engineer role in 3DEXPERIENCE provides powerful tools to simulate complex physical phenomena, but how you manage your models and analysis cases can greatly influence your workflow and outcomes. One simple yet highly effective technique is duplicating your FEM models and analysis cases.

Duplicating FEM models allows you to test different materials or mesh settings without altering the base geometry, while duplicating CFD analysis cases lets you explore various flow conditions, boundary settings, and solver parameters using the same mesh. Together, these techniques streamline your studies and ensure consistent, comparable outcomes.

Finite Element model for CFD consists of information’s related to the mesh and material properties used in the simulation.

Reusing Geometry for Material and Mesh Variations

In engineering simulations, the geometry of your model often remains constant, but the material and the mesh settings can vary widely.

For example:

By duplicating the FEM model, you keep the original CAD geometry, and only swap the material assignment and mesh densities in the duplicated model.

In many FEM simulations, the geometry remains unchanged while you test different materials or mesh configurations. By duplicating the FEM model, you can easily change material properties such as switching between steel and titanium, or exploring various polymers without modifying the original setup. You can also adjust mesh parameters like density, element type, or refinement. This method maintains consistency across tests, accelerates the setup process by reusing the same CAD model and boundary conditions, and enables direct comparison of results for material selection or mesh sensitivity studies, all while preserving your baseline model.

It consists of information’s regarding the wall conditions, loads, contact information’s and step definitions.

In Computational Fluid Dynamics (CFD), it is rare that a single simulation tells the whole story. Engineers often need to run multiple scenarios varying flow rates, boundary conditions, or turbulence models to fully understand fluid behavior. In the 3DEXPERIENCE platform, one of the most efficient ways to manage this is by duplicating your analysis case.

In CFD, duplicating an analysis case lets you keep the same geometry and mesh while testing different simulation scenarios quickly and consistently. You can vary flow conditions (such as inlet velocity, pressure, or temperature), modify boundary conditions (like outlet pressure settings, wall treatments, or symmetry planes), try alternative turbulence or physical models (k-ε, k-ω SST, laminar vs. turbulent, heat transfer, or multiphase flow), and adjust solver settings (time step size, convergence tolerances, or steady-state vs. transient). This approach isolates each change for accurate comparison, speeds up setup, and preserves your baseline, making it ideal for sensitivity studies, validation work, and performance optimization.
