Wind Engineering (WE-UQ) / recorders not generated
« on: March 30, 2021, 07:37:07 AM »
Hi,
I am using OpenSees model of the 20-story SAC building in 2D as an input for WE-UQ. The model has a lot of elements and nodes, so I used the "user defined" option in the EDP section. If I use the "standard wind" option, Dakota will give me an error saying that "expected function values are not equal to the values found".
When using the user defined option, I modify the "recorder" and the "postprocess" files found on the website for the 9-story SAC building to just give me the results for the displacement at some node at roof level of the building. But no matter how I change the recorder and postprocess files, when I run the program, no disp.out files are generated for me in the work directories. Accordingly, I get zero and NAN values for the forward propagation analysis results. Could there be another reason for the zero and NAN results? I am using a stochastic wind event.
This is what I have in the recorder file:
recorder EnvelopeNode -file disp.out -node 1123 -dof 1 disp
This is what I have in the postprocess file:
set dispIn [open disp.out r]
while { [gets $dispIn data] >= 0 } {
set maxDisp $data
}
# create file handler to write results to output & list into which we will put results
set resultFile [open results.out w]
set results []
foreach edp $listQoI {
set splitEDP [split $edp "_"]
set response [lindex $splitEDP 0]
set tag [lindex $splitEDP 1]
set dof [lindex $splitEDP 2]
if {$response == "Disp"} {
set nodeDisp [lindex $maxDisp 0]
lappend results $nodeDisp
} else {
lappend results 0.0
}
}
# send results to output file & close the file
puts $resultFile $results
close $resultFile
