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
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 fire fluid dynamics analysis with BlenderFDS. This is possible via the 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
If you are so lazy that you don’t want to waste time entering the CloudHPC platform, the CFD FEA Service calculation service, then you have to use the python application created ad hoc for this operation. This allows you to execute code Aster from Windows without having the solver installed 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
CloudHPC is continuously committed into expanding the range of software available on our platform. This autumn, the range of CFD, FEA and FEM software available to users is expanding with a new tool dedicated to mesh generation: cfMesh+ cloud. This tool is dedicated to generate mesh for OpenFOAM and similar 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
You have run your simulation with code_aster FEM on the cloud and it is converged and now you need to post-process the results.The results files are several hundred GB and you don’t want to saturate your internet bandwith. This could be a tipical cloud computing scenario. You absolutely need to Read more
