PyroSim 2022.1 will release this week with several new features. One that we’ll highlight today is the new mesh assignment optimization algorithm. When a model is designed with multiple meshes, they are assigned to separate cores for simulation. This parallel process helps reduce the total time needed. When there are more meshes than processors, an algorithm is used to determine an efficient pairing. … Read More
PyroSim has previously offered many ways to help users create the most efficient meshes for their models by providing cell calculations, a refinement tool, and a splitting tool. In PyroSim 2014.4 we will introduce mesh partitioning, which automatically divides one or more meshes into equal cuboid parts. This is useful when taking advantage of multi-core processing via the Run FDS Parallel action, where meshes can be assigned to individual cores. … Read More
Scenarios were previously introduced to PyroSim as a tool to help repurpose assets within a model for various use cases. If you’re not familiar, you can read their original introduction or view the User Manual documentation to learn more. In the upcoming PyroSim 2021.4, users will be able to select which scenarios get exported before creating the batch file. … Read More
Hydrogen cyanide (HCN) reactions were added in FDS 6.7.6 and are supported in PyroSim 2021.3. As part of this update, we have added HCN support in our Combustion Calculator which helps solve the stoichiometric equation to define a reaction. This calculator is provided as a free download with an included tutorial. … Read More
An issue in the PyroSim toolbar was recently identified. When results are available for viewing, the View Results and Plot Results buttons are disabled. This issue was introduced in the 2021.2.0525 release of PyroSim.
We have identified the problem, and have uploaded a patch release which addresses the bug. The updated version of PyroSim is available now.
One of our Reseller Partners identified an issue when dragging items in the navigation view. When this happens, the application freezes and requires a forced shutdown to proceed. This issue was introduced in the 2021.2.0512 release of both PyroSim and Pathfinder.
We have identified the problem, and have uploaded patch releases that addresses the bug. The updated versions of PyroSim and Pathfinder are available now.
PyroSim 2021.2 includes usability improvements to better monitor FDS simulation progress and find objects in your model.
Added the ability to scroll away from the bottom of the Run FDS Console
PyroSim 2021.2 includes an improvement to the Run Simulation dialog. In the new version, the FDS output in the Run Simulation dialog is prevented from dragging the user’s view along with it. This is useful if a user would like to examine a particular portion of the output while the simulation is still running.
Search with “whole word” and “case sensitive” options in Find dialog
PyroSim 2021.2 includes an improved Find dialog. This improved dialog includes the new “Whole Word” and “Case Sensitive” checkboxes, which constrain content matches to exact matches of the search term and case sensitive matches of the search term, respectively.
What is cloud computing?
Cloud computing is a tech industry term for a service which provides computing power on request. This service is provided remote, or “in the cloud”, so that the user can access these resources from their office. One common use for cloud computing is to gain access to powerful hardware which goes beyond the needs of day-to-day office work.
Why use cloud computing for FDS?
FDS simulations can require over a full 24 hours for large, complex, or long applications on a modern business PC. This brings several challenges. Some models may exceed the memory limitations of a desktop machine and are unable to complete.
Not all projects demand such a long amount of time. Many can be simulated within a single working day, while others can be split or coarsened in order to design iteratively. For some users, their needs never exceed these situations. It can be simpler and cheaper to maintain a local machine to process simulations of this scale.
For others, cloud computing simplifies an otherwise complicated purchase of a high up-front cost server system to scale with increasing needs. Services across many industries offer on-demand computing power with simplified billing and on-demand power. In either case, a modeler may simply want to offload their computing needs so that their main desktop or laptop can be used for other tasks while the simulation completes.
How is cloud computing used in PyroSim?
Cloud HPC now provides FDS on Cloud for the fire simulation industry. This service supports multiple FDS versions (including the most recent), scalable virtual CPU power to meet your needs, and the ability to monitor your simulation progress in real-time.
PyroSim supports the ability to run an FDS simulation in the cloud by integrating with CFD FEA Service’s Cloud HPC. The user inputs their credentials and desired provisions for the cloud instance. Once the simulation begins, users can use the cloud provider’s dashboard to manage their progress. To view pricing and receive more information, register with Cloud HPC.
