Title: rhoSimpleFoam for stationary compressible turbulent internals flows

Posted December 9, 2020 at 05:01 by dlahaye

1/ Introduction

The scope of these notes is to discuss the simulation of stationary compressible turbulent flow in OpenFoam using the rhoSimpleFoam solver. We assume the reader to be familiar with the concept of stationary incompressible turbulent flows and the simulation of these flows in OpenFoam. This allows us to focus here on the transition from incompressible to compressible. We target internal flow with Mach number between 0.4 and 2. The application to external flows and/or...

Problem installing OpenFoam-v1912 from source on Mac with Clang

Posted November 15, 2020 at 11:06 by wangsen992

This problem bugged me for the whole day. Ultimately the reply from below saved my night.

However, i don't like the new file system solution since you could simply run a virtual box or a docker which are basically the same but much more elegant and portable. I want to have some approach that can install openfoam locally, and be used as a library instead of working in a separate environment.

the Nyquist theorem says that for a step sampling dt you can describe the smallest wavelenght 2*dt (three samples describe a sine). For a given period lenght T, the ratio T/(2*dt) gives the maximum wavenunber you can represent
