envelope record command doesn't work in opensees 1.6.2

chjjj · Post by **chjjj** » Sat Apr 23, 2005 12:32 am

When I use the EnvelopeElement command in the opensees1.6.2, the output file is empty.

But when I change to use the opensees1.6.0, it did work.

If there are some problem with the command, or the syntax has been changed?

Thanks

i believe the syntax has changed.
what is your command?

my command is:
recorder EnvelopeElement -file $dir/section/ele$i/sec${nP}Force+Defor.out -time -ele $i section $nP forceAndDeformation

thanks

have you tried something other than forceAndDeformation??

it is an old undocumented feature of the old version, now you should ask for force and deformations separately.

this is a part of my record file.
#column section recorder
for {set i 1} {$i <= 72} {incr i} {
file mkdir $dir/section/ele$i
foreach nP [list 1 $colnP] {
recorder EnvelopeElement -file $dir/section/ele$i/sec${nP}Force+Defor.out -time -ele $i section $nP forceAndDeformation
}
}

#beam section recorder
for {set i 73} {$i <= 174} {incr i} {
file mkdir $dir/section/ele$i
foreach nP [list 1 $beamnP] {
recorder EnvelopeElement -file $dir/section/ele$i/sec${nP}Force+Defor.out -time -ele $i section $nP forceAndDeformation
}
}

#beam reinforcement stress-strain recorder
for {set i 73} {$i <= 126} {incr i} {
file mkdir $dir/Cstress-strain/ele$i
foreach nP [list 1 $beamnP] {
recorder EnvelopeElement -file $dir/Cstress-strain/ele$i/sec${nP}CstressStrain01.out -time -ele $i section $nP fiber [expr -$y3] 0.0 stressStrain
recorder EnvelopeElement -file $dir/Cstress-strain/ele$i/sec${nP}CstressStrain02.out -time -ele $i section $nP fiber $y3 0.0 stressStrain
}
}

and none of the three works??
have you tried removing the -time argument??

also, i woulnd't use the + in a filename string.

since I cant' really run this short segment, I have a question:
what's up with the following piece of filename:
sec${nP}For
in $dir/section/ele$i/sec${nP}Force+Defor.out

shouldn't the $ be insied the {}????

Take the Example5.1 for example: (OpenSees Examples Manual)
I add a recorder to the source file, like:
recorder EnvelopeNode -file Envelopenode51.out -time -node 9 14 19 -dof 1 2 disp

The file(Envelopenode51.out ) is empty.

Hi,

I was having this problem as well. Frank suggested adding a wipe at the end of the input file and I am able to get output. There is another thread regarding this issue, way back on this message board.

so i guess opensees is not closing the file.
the wipe at the end should solve the problem, please let me know if it does not.
thank you Jayram!!!
good reminder to do searches on this forum.
