to get compatible element forces & deformations

Post by talebian.s.e » Fri Sep 11, 2009 1:32 pm

hi,
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.
