warning, wipeAnalysis not invoked

Post by dangdang »

Hi guys.
when i run Opensees, even if run simple model, that says
"Warning: analysis .. exisiting TransientAnalysis exsts => wipeAnalysis not invoked, problems may arise"
actually i always use 'wipe' and 'wipeAnalysis' before using 'source'command.

Here is my simple script

set m 5.0
set A 100.0
set I 100.0
set E 10000.0

set L 20.0

model BasicBuilder -ndm 2 -ndf 3

node 1 0.0 0.0 ;
node 2 0.0 $L ;

fix 1 1 1 1 ;

mass 2 $m $m 0;

set TransfTag 1;
geomTransf Linear $TransfTag ;

element elasticBeamColumn 1 1 2 $A $E $I $TransfTag;

set numModes 1
file mkdir MODE;

for { set k 1 } { $k <= $numModes } { incr k } {
recorder Node -file [format "modes/mode%i.out" $k] -nodeRange 1 2 -dof 1 2 3 "eigen $k"
}

set lambda [eigen $numModes];

set omega {}
set f {}
set T {}
set pi 3.141593

foreach lam $lambda {
lappend omega [expr sqrt($lam)]
lappend f [expr sqrt($lam)/(2*$pi)]
lappend T [expr (2*$pi)/sqrt($lam)]
}

puts "periods are $T"

set period "MODE/Periods.txt"
set Periods [open $period "w"]
foreach t $T {
puts $Periods " $t"
}
close $Periods

integrator LoadControl 0 1 0 0

test EnergyIncr 1.0e-10 100 0

algorithm Newton

numberer RCM

constraints Transformation

system ProfileSPD

analysis Static
set res [analyze 1]
if {$res < 0} {
puts "Modal analysis failed"
}
---------------------------------------------------------------------------------
What is problem? Thanks you for your help.

You don't seem to have a transient analysis in the script that you posted here.

Hey, I am also getting the same warning "wipeAnalysis not invoked". How did you solve it.

There exist two analysis states, period and static. If you only execute static, that's well.
