SPH-flow offers coupling to Abaqus for fluid-structure interaction (FSI).
The motivation is to provide fluid-structure co-simulation: the structure with Abaqus and the fluid with SPH-flow. The targeted applications are those for which fluid is very dynamic and structural deformation is high, and for which simulations with traditional CFD method (Finite Volume) are not sufficient.
Indeed, SPH-flow implements the SPH method (Smoothed Particle Hydrodynamics), a next-generation CFD numerical method based on a Lagrangian (in the sense of connectivity) meshless approach. This approach, combined with an intrinsic consideration of the free surface, is particularly well suited for fast dynamic flows with complex deformable boundaries or interfaces with fragmentation/reconnection, flows which are not easily accessible to classical mesh-based methods. The purpose of this method is to simulate these specific flows and not to supplant established methods such as Finite Volume, which are the basis of current major commercial software (Fluent, CFX, STAR-CCM+...).
SPH-flow is one of the most advanced solution based on the SPH method. It is jointly developed with some of the most advanced research groups working on the method. It is therefore a reference in terms of precision and quality of results. It is commonly used in automotive applications such as oil flow in gearbox, aerospace applications such as ditching or marine applications such as slamming (water impact).
