Simcenter Nastran Co-Simulation: Disc Valve

To solve fluid-structure interaction problems, you can couple Simcenter STAR-CCM+ and Simcenter Nastran in a co-simulation analysis. Simcenter STAR-CCM+ computes the flow solution and Simcenter Nastran computes the structural analysis for the solid.

In this simulation, you analyze the fluid-structure interaction between a fluid flowing through a pipe and a solid disc valve located inside the pipe. Simcenter STAR-CCM+ computes the fluid pressure and wall shear stress at the fluid-structure interface. Simcenter Nastran calculates the displacement of the valve in response to the applied fluid loads. During the co-simulation, each application uses the solution from the partner application to obtain accurate boundary conditions.

As the system is symmetric, you only model a quarter of the full geometry:
