The tasks we spend most of our time and effort on are fluid-thermal (coupled CFD) simulations. Over the years we have acquired a number of cutting edge tools in this field. Our Simulation areas of concentration are:
Fluid Sumulation
Fluid analysis of a system allows questions related to pressures, velocities, flow rates and similar items to be answered. A flow or fluid simulation is usually performed when a system has hydraulic lines, takes advantage of air cooling, or is in general concerned with its performance from a fluid flow and fluid interaction standpoint.
Thermal Simulation
Thermal analysis can be roughly divided into two categories: thermo dynamics and heat transfer. Thermo Dynamics deals with items such as overall or system performance of air conditioning systems, turbine power plants, heat pumps, etc. Heat Transfer on the other hand deals with the localized effects of thermal energy which can find application in the design and analysis of heat sinks, heat loss in pipes, rate of heating or cooling, heat radiated from hot objects, heat loss (or gain) in buildings and similar items.
Structural / Motion Simulation
The most common types of structural analysis performed are numerical analysis on an existing CAD model where the desired information relates to the part's overall deflection or stress points under a given load and constraint. A simulation like this will require that the attachment point or constraints are known as well as a definition of the loads both by location and magnitude. Loads can be applied over faces of an object, lines/edges or points and will always consist of a magnitude and direction. Constraints on a system are what defines how a part is fixed in space. If the system isn't sufficiently constraint, it can move, therefore invalidating the underlying mathematics. The simplest form of constraint is to fix a face in all six degrees of freedom. This means that that particular face cannot translate in the X,Y or Z direction and is also prohibited from rotation around the X,Y and Z axes. During numerical simulations, these values are explicitly enforced at the points that define the geometry.
