Error: Biomass Succession with Fire extension

[Anastasia Popova]

Dear LANDIS-II users and developers,

Has anyone meet an error with Biomass Succession and Fire extension?

I use Landis-II 7.0, Biomass Succession 6.0 and try to use Base Fire 4.0. But I got error even when running on example files (I downloaded it from Biomass Succession site) without changes. I tried to use Dynamic Fuels & Fire System and got the same error too.

What I get in log:

Running Base Fire ...
Processing landscape for Fire events ...
Internal error occurred within the program:
Object reference not set to an instance of an object.
