Introduction to Turbulence Modeling in general and capabilities within STAR-CCM+


Turbulence modeling is arguably the most challenging aspect of computational fluid dynamics. The choice of turbulence model, that is the mathematical representation of turbulence, can have profound consequences on the accuracy of a numerical solution.
This choice is directly dictated by your understanding of different turbulence models and the physics they attempt to represent.

In this webinar (~80 minutes), you are given a deep dive under the hood of STAR-CCM+ to gain insight into the foundations and underpinnings of different turbulence models. You learn about their assumptions, advantages and limitations.

The session covers statistical (RANS) and scale resolving approaches (DES, LES) along with extensive details on near wall turbulence and its numerical treatment.
