CONVERGE Training

CONVERGE is an innovative multi-purpose CFD software that can provide insight into internal combustion engines, compressors, fans, blowers, pumps, fuel injectors and sprays, aftertreatment systems, gas turbines, biomedical devices, oil and gas applications, and many other systems. This two-day course offers a hands-on introduction to CONVERGE. You will learn about the CONVERGE solver and modeling options while working through a wide variety of example cases.

These approaches are applicable to a wide range of conditions, for compressible or incompressible flows, two-phase or three-phase flows, and with two or more species. We will cover how these methods can be used in conjunction with various sub-models to simulate complex phenomena such as cavitation, boiling and condensation, and mixture separation.
