Blender FDS gives you the tools to generate a geometry directly with edit commands available. However, for complex geometry the software allows you to import CAD models such as STL file. In this post is shown how to generate Read more…
PrePoMax (https://prepomax.fs.um.si/) is an opensource user interface to Calculix. Thanks to this, you can easily generate the input file to use for any Calculix analysis. Once the input file is generated, it is also possible to benefit of remote Read more…
CloudHPC is a very special environment. As you would expect from a cluster it is possible to execute several CFD and FEA/FEM analysis using engineering simulations software. Differently to many other providers, on cloudHPC you can also execute preprocessing 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 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…
