Smokeview crashes with a second fire

[BTW72]

When I add a second fire to CFAST, Smokeview is not able to provide the visual solution. I even used the Large Building example. It runs with one fire but add a second fire to the South Office and Smokeview crashes.

Can you post a simple input file (*.in) that demonstrates the problem.

I'll take a look

[gforney]

can you post text files

Copy file.in to file.in.txt and drop it into the window.

try smokeview posted here

let me know if you still see a problem.

to verify you are using the right smokeview - type: smokeview -v . you should see something like this. The important text is the string 6.10.6-241 .

This version of smokeview does allow the second fire and temperature profiles to be viewed. However, the first fire does not show. The temperature profiles are viewable, but the fire itself is not.

I also ran this version of smokeview on another file. It works sometimes but not always. I have added the input files to that evaluation.

fire visibility problem should be fixed in smokeview posted here. i wasn't able to reproduce the random crash issue you were seeing. if you are still seeing it - try to see if you can reproduce steps to make it happen. if we're lucky the crashes were due to the 2 lines of code I took out

Looks like everything is working with this version of smokeview. Tried all four simulations that I shared, and all of then worked. Thank you for your help.

[gforney]
