KrylovNewton

Post by mohsenkh »

Dear

I modeled RC moment frame (2-D). Beams and columns were modeled by forceBeamColumn element. Analysis is nonlinear time history. The transient analysis were applied as following:

#-----------------------------------------------------------
# Transient Analysis
#-----------------------------------------------------------
loadConst -time 0.0

.
.
.
wipeAnalysis

set tFinal [expr $NumTransiant*$deltaT]
set Tol1 1.0e-4

test NormDispIncr $Tol1 1000
algorithm KrylovNewton
integrator Newmark 0.5 0.25
system ProfileSPD
constraints Transformation
numberer RCM
analysis VariableTransient
set ok [analyze $NumTransiant $deltaT [expr $deltaT/100]$deltaT 1000]

% ----------------------------------------

Can I use the KrylovNewton algorithm as I display this algorithm as top? Is this right? Can anyone introduce example that explained the KrylovNewton algorithm?

Thanks.
