STAR-CCM+ offers practical solutions for tackling fluid structure interaction problems in the Life Sciences Industry
Fluid-Structure Interaction is the study of thermo-mechanical interactions of a fluid and a solid structure. STAR-CCM+ provides several approaches to FSI, leading to practical solutions for analyzing problems where biological fluids interact with flexible tissue (e.g. blood and vessel interactions, air and lung interactions)
  • CFD Methods in the Biomedical Device and Diagnostics Industry
    Biomedical device design is facing increasing product complexity while prototype building and testing can take months. The inherent risk in new medical product development can be mitigated through a deeper understanding of the design properties and functions achieved through modeling and simulation. This webcast covers and addresses the benefits of engineering simulation. Experts discuss modeling capabilities for the design of various devices from...

STAR-CCM+ has a direct link to Abaqus FEA through co-simulation, delivering fully coupled, two-way, fluid-structure interaction. STAR-CCM+ co-simulation gives users the flexibility to choose between explicit and implicit coupling, depending on the application. The implicit coupling approach is particularly beneficial for applications in the Life Sciences Industry because of the complex cross-coupling between the biological fluid and the highly flexible tissue. 

In addition to direct co-simulation, STAR-CCM+ also enables FSI computations through importing/exporting meshes in other native formats (e.g. Nastran/Ansys) as it leverages the power of JAVA and gives users the ability to customize every step of the work flow.

The built-in mapping implemented in STAR-CCM+ is robust and accurate and efficiently handles non-conformal meshes with no need for writing scripts or input files.A multi-quadratic morphing capability robustly and smoothly moves the meshes (of any topology) based on the deformation it receives from the structures solver. The resulting mesh conforms to the shape of the deflected structure and the redistribution of the mesh vertices nicely preserves the quality of the original mesh. In addition to mesh morphing, STAR-CCM+ also has an overset mesh capability.

Using the FSI capability in conjunction with STAR-CCM+'s unrivaled meshing technologies, high-fidelity multi-physics and intuitive user environment results in an FSI capability that is flexible, accurate, robust and efficient.
