[Libmesh-devel] Trouble using large number of variables (>=256).

[Vijay S. M. <vi...@gm...>]

Hi,

I probably never noticed this before but a weird bug hit me while
trying to run a system that has more than or equal to 256 variables.
The Debug assert in line 256 of DofObject.C, is responsible for this.
This check throws an error in Debug mode (not in other modes of
course). I do understand that the unsigned char is there for
efficiency sake but is it possible somehow to break this variable
limit ?

I was originally planning on changing this data type for _n_v_comp to
do this but wasn't sure if that would be the only change needed and if
there are some dire consequences due to it. Also, if anyone has solved
some system with these strange requirements, I'd be happy to hear
about your experience.

Thanks,
Vijay
