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…
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…
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…
CloudHPC data security is a very important task to guarantee. In an cloudHPC system like ours we often deal with massive data coming from engineers which can be under NDA (Non Disclosure Agreement) between users of our platform and their clients or protected by patent. For this type of situation Read more…
A fundamental stage in FDS to achieve a good scalability regards the use of MPI (also named multicore) parallelization method. This method, as we highlighted in an old post, is based on the MESH definition in the input FDS file. To achieve a good scalability it is fundamental you split Read more…
On cloudHPC it is possible to execute code_aster cluster with OpenMPI. This means the process is going to be divided among the cores available on the instance so your simulation can proceed faster. When executing MPI processes it is mandatory to “split” the mesh: the parallelization in fact works that Read more…
Many users wonder how which procedure follows our snappyHexMesh script. The reply to this question is rather simple and this post aims at giving you the most important info. basic steps to generate mesh with snappyHexMesh Obviously to use snappyHexMesh there are three steps to follow and complete: blockMesh – Read more…
