is ther any way (through PyroSim or FDS)to set some kind of Ignition flux, like there is an Ignition Temperature,

I'm having trouble opening a results file from a pathfinder simulation. I get an error message that states:

"Could not load results: Could not load occupant animation file: <file name>
Reason: Could not open file."

I tried uninstalling and reinstalling the software, and setting the rendering preferences to maximum compatibility and rerunning, but still got the same message. Help!

Hi. I hope this is a simple question. I am new to FDS.

So a colleague of mine has left and has handed me some simulations that have already taken months and have months more to go. The meshes were not divided up, it is just one huge mesh. It is an eight core machine, with 1 MPI process and 6 openMP threads. I just turned off hyper-threading and restarted.

So as I understand it, there is no point in using MPI, so is there an advantage to disabling it (if that is possible)? and only use OpenPM.

To be honest, I am a bit confused, if I have 1 MPI process, does that mean that the simulation is running on just one core? As the PC has one core constantly at 100%. whilst the other cores, are jumping between 10 and ~90% (but all 7 cores, not just the other 5, also confusing) .  So I am not even sure if the OpenMP is using all 6 cores, or if MPI has forced it on to a single core.

Thanks, I hope that is clear,

Is there an easy way to delete a node while creating the navigation geometry, or deleting nodes from imported geometry that has been extracted?

I understand that the "remove extra verticies" option exists, but most often that does not delete all the extra unnecessary nodes.

Thank you for the feedback, I think you will be happy to learn that if you use the 'Select and Manipulate Objects' tool (instead of 3D Orbit), then the left mouse button is used to select/manipulate objects (and drag select), right-click drag enables 3D orbit mode, middle mouse button (pressing the scroll wheel) enables the pan tool, and scrolling the wheel zooms in and out on the model.

Also, we are very close to releasing a new feature for user-customizable Keyboard Shortcuts.

Hi guys,

Can someone please give me an example input for a jetfan to put into my FDS simulation, in which all I would have to do is change the velocity output and dimensions?

I am not using pyrosim just directly into FDS. I have been trying for hours following examples and user guides with no luck. I am still a novice with FDS.

Any help would be appreciated.

I have a request to help improve navigating the 3D view interface. Similar to Sketchup, can you please consider adding the functionality that if "3D Orbit Navigation" is selected, it is possible to toggle to "Pan View" when both the middle and left mouse buttons are simultaneously held down. Once released, the selection then returns to "3D Orbit Navigation".

I find this much easier and faster to inspect and navigate a model with this functionality added.

Also, providing keyboard shortcuts for all toolbar buttons would help to drastically improve the speed that models can be built and navigated.

Thanks! and keep up the great work!
