Possible bug in pyrolysis model?
 

Hello Foamers.

I'm using OF 2.1.x. I noticed a very strange behavior in the total heat release rate (HRR) when running solver fireFoam and the case oppositeBurningPanels (with minor modifications to run faster), as shown below:

number of layers ................HRR (J/s)
of extruded panel ...............at t=5s
----------------------------------------------
10 ....................................-13214
5 (case default) ...................-6641
3 .......................................-1173
2 ..........................................-29
1 .............................................0

If the cases are exactly the same, except for the number of layers of the extruded panel, shouldn't I expect the same HRR? Is there a bug or am I missing something?

The panel depth is 0.01m in all cases.

Thanks,

Paulo
