Jet Fans are commonly elements present in car parks. They are elements whose goal is moving air, smoke and heat in case of fire towards an extraction point. JetFan model is FDS is a strategic choice when running a fire scenario. Jet Fans applications is quite common in indoor car Read more…
FDS has default settings on how to deal with thermal radiation transport in the simulation. However, there are some simulations where reducing the ration calculations can be useful to reduce simulation time. Such as per simulation where there aren’t high change in temperature or in external fires. Otherwise, knowing the Read more…
FDS provide different methods in order to stop your running simulation: SOFT and HARD STOP. Sometimes your analysis just crashes and you would lose all of your data. Other times, you might want to stop a calculation, make few variations, and restart the simulation from when it left off. FDS Read more…
An Important FDS feature is the ability to restart a simulation. The Cloud HPC allows you to restart your simulation directly from the web-app, with the MISC parameter RESTART. When running a simulation, there could be times in which you need to stop your simulation, in order to make few Read more…
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…
