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 a complex geometry starting from a STL file. Blender FDS allows 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 to be able to run the simulation. Blender FDS tool is 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 Technology (NIST). FDS is computational fluid dynamics (CFD) model. BlenderFDS helps 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 for CFD, FEM and other simulations. The High Performance Computing system 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 it may happen that you rin into the following error: The 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 some unphysical behaviour such as very high velocity or very low Read more
A useful feature of the Cloud HPC Service is the possibility to access to Smokeview and check your results live directly from the webapp. The Cloud HPC System allows you to run large and complex FDS analysis by renting the needed computational capacity and to easily manage your simulation directly Read more
Often users ask how much a simulation on cloudHPC is when using FDS. To this question the reply is generally articulated and this post investigates the main parameters that influences your simulation cost. cloudHPC pricing First of all, it is important to remind you how cloudHPC pricing works. Compare to Read more
CFD FEA Service offers the Cloud HPC service to run your FDS scripts for computational fluid dynamics simulations. The offered service allows you to manage your FDS script and your simulation completely online from the web-app. From the web-app it is possible to edit your FDS File online and the following Read more
In FDS, the calculations are performed within the set-up domain defined by the meshes. A mesh is a volume formed by rectangular cells. The number and size of the cells define the desired resolution of the mesh and therefore of the calculations. This post aim to give an overview about Read more
