..WARNING..

Post by Elina »

Hello! It's my first attempt to use Opensees and I find it quit powerful !!

I'm trying to analyse a building similar to the one in example 8 but i'm confused with a Warning:
"WARNING - ForceBeamColumn3d::update - failed to get compatible element forces &
deformations for element: 20100(dW: << 3.28314, dW0: 3.2832)"

this comes up for every column of the building....can you help me?

Thanks!! :)

it is a convergence problem, but the script changes analysis parameters and gets over it, doesn't it???
