Hello everybody.

I was wondering is there any chances to make a big fire (like 10x10m) and add one sprinkler in the middle to see the extinguishing area of sprinkler using a temperature slice ?  If someone already tried something like that please share your opinion.

At first glance, there are a couple of problems. A sloped surface can't be modelled. (It would look sloped in PyroSim, but would be stair-stepped in FDS. It's not possible to have anything move in FDS. You could create a series of burner vents to progressively appear on the descending steps to simulate the fuel flow, but you would be prescribing the events, FDS would not be modelling them.

I'm trying to model a fuel fire on a sloped surface. (fuel spill on a bridge) The flow will lead to a drain.  Is there anyway to model the burning fuel flowing into a drain in PyroSim?

I had the same problem and found the solution in changing the regional settings in Windows before opening the FDS-generated csv file (I'm based in Germany)
Make sure to set the format under regional settings to "English". Windows has also recognized the problem:

 The early stages are the same for all models. Can I start the models from 500 seconds, changing the single parameter once i have run one model fully?

That shouldn't be happening. Excel has recognized .cvs files and automatically parsed them out for at least the last 10 years. When you look at the folder in Windows Explorer, you should see the Excel symbol beside all of the .cvs files.

If you don't, then change the file association.

right-click -> Properties -> General -> Opens with -> Change -> select Excel

After that, just double click the file to open it in Excel, with the columns properly parsed.

I want to plot the measured HRR and temperature with a line in excel. I have opened the filename_hrr.csv with excel, but all the numbers are copied in the same cell. Is there an easy way to extract only time and hrr from that cell, or do I have to manually copy what I want from each cell for different times?

There is probably an elegant way to do it with custom controls.

This is the inelegant way.
I'm assuming there is enough room in the roof to make duplicates of all of the vents, so that there are pairs. (I'll refer to them as set A and set B.

Have all of the set A vents activated by individual heat detectors.

Have all of the B vents activated at the same prescribed time.

At the prescribed time, when all of the B vents are activated, also create obstructions that block all of the A vents (whether they had been created or not).

That should be equivalent to what you want.
