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 Read more…
CalculiX is a free and open-source software package for finite element analysis. Engineers and scientists can use it to solve complex problems in fields like structural mechanics, heat transfer, and fluid dynamics. CalculiX can handle both linear and nonlinear Read more…
Meshes define the computational domain of your simulation. Multiple meshes are useful to assign the work load to different cores, achieve a good scalability and optimize the simulation. However, it is fundamental to properly aligned abutting meshes in order Read more…
Blender provides an add-on named BlenderFDS a graphical interface for FDS which allows to set and manage complex geometries and FDS input parameters. FDS is a free and open-source software tools provided by the National Institute of Standards and Read more…
FDS simulation results ran in the Cloud HPC are available through the web-app STORAGE. Visulizse the FDS results by means of the Pyrosim results application. The Cloud HPC service is offered by CFD FEA Service to run your scripts Read more…
ERROR: FDS MPI_PROCESS In the past we highlight how you can set your FDS analysis correctly to reach a good scalability. Often this involves using the MPI_PROCESS parameter to correctly split the workload among different processors. When doing that Read more…
ERROR: Numerical Instability - FDS stoppedIf you run an FDS analysis, it may have happened to step into an error similar to the following one: This error represents a numerical instability: it means that FDS, during the computation of the fluid flow field, obtained Read more…
Blender provides a graphical interface for FDS with the advantage of being able to share BIM geometric data. Importing and converting IFC to FDS models is a useful way of incorporating complex designs into Blender for the development of 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, 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 Read more…
