- Rigid Body Simulation: Both bodies behave like rigid bodies, and the impact is completely elastic. This is referred to as a so-called Rigid Body Simulation (RBS).
- The falling beam remains a rigid body and the second body behaves linearly elastic (Hooke's law), i.e. it can deform geometrically. This is already a real Structure-Structure Interaction (SSI) Simulation. Since one body is still rigid, one speaks of a one-sided structure-structure coupling.
- Both bodies behave like elastic solid bodies and deform due to the collision. In this example, linear elasticity was assumed for both bodies, but all other non-linear structural laws can also be used (e.g. Maxwell models).
This model can act as basis for more complex structures and will give you a better understanding of the fluid structure coupling and helps to improve your design regarding efficiency and costs.
NOGRID points can perfectly be used for designing and problem solving for all kinds of FSI processes. The structure deformation, the temperature and the cooling/heating rate can be predicted. NOGRID points helps to understand the flow by visualization of the mass, momentum and heat transfer of single and multiple phases. You receive integral quantities which you can use to analyze the SSI process efficiency.
NOGRID unites abilities to handle FSI problems and allows the simulation of any conceivable geometry and operation modes such as
- computation is in full 3D solving complete Navier-Stokes-Equations
- easy and intuitive setup also for SSI (Structure-Structure-Interaction) cases
- free definable material properties by equations or curves
- evaluation of chemical reactions and corresponding heat source terms
- open or closed domains including inflow and outflow areas (non-batch mode)
- moving of parts

What is CFD from NOGRID?
CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID software for flow modeling you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
