I have modeled a 3 story frame to perform dynamic analysis,when i run it,this occurs: "forcebeamcolumn2d::update - failed to get compatible element forces & deformations for element 10<dw:<<63.4965>
domain:update - domain failed in update
newmark::update<>-failed to update the domain
newtonraphson ::solvecurrentstep <>- the integrator failed in update <>
DirectintegrationAnalysis ::analyze <>-the algorithm failed at time 1.4
Analyze failed, returned -3 error flag"
what could it be?
thanks so much.

it's a convergence problem.
compare your script to the ones in the examples manual.
