Simcenter STAR-CCM+

Marine FSI

The higher an uncertainty the more conservative a design. Eliminating uncertainties makes it possible to develop products which are safe, but not overly conservative in their design. This is why it is important to compute fluid loads on structures, rather than making highly uncertain assumptions about them. Luckily Simcenter STAR-CCM+ comes with an integrated solid …

How to set up a FSI simulation in Simcenter STAR-CCM+

This week we will take a closer look at the settings for using fluid-structure interaction (FSI) in Simcenter STAR-CCM+. This blog post is inspired by the tutorial Diaphragm valve, found in the documentation for the latest release of Simcenter STAR-CCM+, 2021.2 (you find the tutorial under Solid stress).  FSI is when you have a two-way coupled interactions between a solid domain and a fluid domain. For example, the solid can be flexible and moving in a fluid. Then the resistance of the fluid will deform the solid. Since …

What if VOF doesn´t work? MMP-LSI

Multiphase flow has been lifted in the latest release of Simcenter STAR-CCM+ to a new level of hybrid modelling to improve computational efficiency. Seven different models for multiphase flow are available in STAR and can be combined to allow us to simulate for applications like Marine Hydrodynamics and Seakeeping, Fuel Cells, Spray Coating, Vehicle Water …

Ship stabilizers damping effect

Simulating motion as a response to forces exerted from flow is a complex and often computationally extensive task. Luckily, in Simcenter STAR-CCM+ we can utilize the DFBI (Dynamic Fluid Body Interaction) module to simulate the motion of a rigid bodies, like ships. Without effort we can expose a vessel to forces from the physics continuum, …

Boundary condition from table input

Importing tables and using them as input for specifying boundary conditions in Simcenter STAR-CCM+

Boundary conditions make our simulations specific to our problem statement. If you want a specific profile of the velocity as input to your simulation (e.g. from test data for example), it is good to know how to import this boundary condition as a table. In this week’s blog post we will show you how to: …
