SCORG® grid generator uses algebraic grid generation for the two rotor domains that deform during the solution. SCORGTM can generate a set of grid files representing the rotor position at successive time steps which can then be used by a CFD solver.

 

Ansys CFX® is a general purpose CFD solver and is capable of interpreting all the grids from SCORG® grid generator. CFX® has a special interface within the solver that is called as Junction Box Routine. A Junction Box Routine reads the mesh produced by SCORG® every time step and provides updated location of the nodes for the deforming rotor domain there by simulating the positive displacement flow field of the machine.

 

A snapshot of CFX® GUI with rotor grid and real machine port grids is shown here. It is also possible to generate theoretical Suction and Discharge ports from SCORG® grid generator in ANSYS CFX® format and can be used for quick assessments of the rotor flow features.
