I suggest a boundary file of burning rate. To make it as clear as possible, in the &MISC line set BNDF_DEFAULT=.FALSE.. (This turns off the display for everything that is not specifically tagged.) Then for each of your car obstructions, use the Advanced feature to set BNDF_OBST=.TRUE. (This tags specific OBSTs to display the burning rate.)

If the OBSTs ignite, then it will be displayed on a cell by cell basis.

Hey!

I'm trying to model fire spread between cars in a car park, but can't figure out how I can monitor when the fire spread to other cars. I've made a layered surface, added the material and thickness in material layers, put an ignition temperature, HRRPUA and ramp-up time. Made a vent on top of each car and put the previously mentioned surface in the vent properties. The beginning fire is of course a burner surface. How can I see exactly when the fire spread to other cars? I need information on the time when the fire spread to car 2, 3, 4 etc.

Hi everyone!

I was wondering if there is a way in Pyrosim to assign for example a hole with two controls. My specific situation is like this: the holes are representing smoke vents on the roof. The hole is to be activated by either a heat detector (seperate detectors for each hole) or manually by the fire brigade which is modelled as an activation after a specific time. I want in this case to assign the holes to be activated either by the heat detector or after a specific time (all of the heat detectors do not acitivate before the fire birgade arrives)

Thanks in advance

Hi everyone,

Does anyone know how we can have access to readymade libraries of Pyrosim except existing ones in the software tool?

Libraries such as reactions, heat detectors, materials, particles, surfaces, and other model parameters.

Thank you so much.

A StackOverflowError is simply signals that there is no more memory available. It is to the stack what an OutOfMemoryError is to the heap: it simply signals that there is no more memory available. JVM has a given memory allocated for each stack of each thread, and if an attempt to call a method happens to fill this memory, JVM throws an error. Just like it would do if you were trying to write at index N of an array of length N. No memory corruption can happen. The stack can not write into the heap.

The common cause for a stackoverflow is a bad recursive call. Typically, this is caused when your recursive functions doesn't have the correct termination condition, so it ends up calling itself forever. Or when the termination condition is fine, it can be caused by requiring too many recursive calls before fulfilling it.

Here's an example:

public class Overflow {
public static final void main(String[] args) {
main(args);
}
}

That function calls itself repeatedly with no termination condition. Consequently, the stack fills up because each call has to push a return address on the stack, but the return addresses are never popped off the stack because the function never returns, it just keeps calling itself. If the stack is full you can't push, if you do you'll get stack overflow error. StackOverflowError is avoidable if recursive calls are bounded to prevent the aggregate total of incomplete in-memory calls (in bytes) from exceeding the stack size (in bytes).

After updating to the latest version Pathfinder don't start and PathfinderResults don't start. Reinstallation 2020.2.0527 does not help, previous version 2020.1 doesn't work either. List of errors in the attachment log. What to do in this case? Updating Java does not solve the problem either.
Program crashes.
