error running parallel

[Unni Kartha G]

I had bult Opensees SP and tried out one of the examples, the cantilever problem, with a small modification.
I am getting the following error

[b]unni@dldap:~$ mpirun -np 2 OpenSeesSP/bin/OpenSeesSP canti.tcl [/b]

your model was too small. i have made changes so that in future you will just exit with a message saying the model was too small.
