Fluids

Any physical process can be described in terms of transport and state. Fluids fit naturally...

CFD solvers utilize transport algorithms and state equation algorithms to robustly model thermofluid phenomena. A conservative form for the transport of species describes the formal state of the system, while primitive variables (velocity, pressure, temperature) are defined by with state and compatibility equations. Users simply points and clicks to select models and apply boundary conditions, while advanced users can customize these functionalities.

Space-time accurate compressible flow modeling applies realtime digital signal processing techniques to the Finite Difference Method (FDM), enabling high-order accuracy on structured grids.

FDM

FVM

Perfect for quasi-steady-state industrial gas modeling, Finite Volume Method (FVM) uses a similar conservative flux approach, whereby spatial integration is performed using median-dual flux to yield 2nd-order accuracy on grids and meshes.
