Installing and Running OpenFOAM with Docker Here’s a breakdown of how to install and run OpenFOAM using Docker: 1. Prerequisites: 2. Find a suitable OpenFOAM Docker image: There are several OpenFOAM Docker images available on Docker Hub. Some popular options include: 3. Pull the image: Once you’ve chosen an image, Read more
In the past posts about simulation schemes and function object, we talked about the possibility of setting a first or second order analysis and the possibility of running custom actions while openfoam is actually executing the simulation. This post is dedicated on automation: update OpenFOAM numerical settings automatically Given the Read more
Introduction Mesh generation is a critical step in the simulation and modeling process for various engineering and scientific applications. Open source mesh generation software has gained significant popularity due to its accessibility and flexibility. In this blog post, we will compare four prominent open source mesh generation tools: SnappyHexMesh, Salome, Read more
The fvSchemes file in OpenFOAM is used to specify the numerical discretization schemes used for different variables in the simulation. It controls the accuracy and stability of the simulation results. To open the fvSchemes file, navigate to the system folder in your OpenFOAM case directory and open the file with Read more
cloudHPC today is releasing the new snappyHexMesh calculator. This is a tool which helps users into choosing the main geometrical parameters of a CFD mesh built using snappyHexMesh, the opensource meshing software included in OpenFOAM. Thanks to this tool, using few parameters, the user can obtain geometrial info about his Read more
As a cloudHPC provider, it is important to give guidelines to users about estimating the cost of using remote hardware resources for one single simulation. Today we talk about OpenFOAM and we discover how you can estimate the cost of one single simulation. Let’s start from scratch: OpenFOAM is an Read more
Many users wonder how which procedure follows our snappyHexMesh script. The reply to this question is rather simple and this post aims at giving you the most important info. basic steps to generate mesh with snappyHexMesh Obviously to use snappyHexMesh there are three steps to follow and complete: blockMesh – Read more
CloudHPC is able to provide a number of real-time information when running OpenFOAM simulations. In particular it gets useful to add some OpenFOAM function object which are able to plot some variables calculated by OpenFOAM. Thanks to these, you can monitor your analysis and it is possible to make a Read more
A design of experiment is a methodology of authomatically execute multiple analysis to verify, for instance, the influence of boundary conditions to a CFD case. Thanks to cloudHPCexec, a linux tool which you can install as a normal .deb package, this is possible and easy to do. Let’s discover how! Read more
