Hi all

anyone using TeraGrid out there?

marco

frank,

could you give me some more details about this trick that you suggested? you mean that I should "fake" a regular time history doing a multiple support analysis with the same motion at the different supports ?

thanks

... ok

I added .0 and it works

31.0 31736.0

thanks anyway

Silvia, Frank, users

why does tcl treat my parameters as integers when I use foreach? the result of the expression epsc0 returns zero instead of 0.00195

foreach {fc Es } {
31 31736 ....
set epsc0 [expr 2*$fc/$Ec]

how can I evaluate that rational while keeping using foreach?

thanks

frank, silvia

was wondering if there was a way to record nodes absolute acceleration

thanks

hi all

is there a way yet to save time and memory with recorder selecting just fewer committed states than in the time history?
say
GM TH steps @ 0.005sec
Recorder steps @ 0.01

thanks

... did it depend on the model or on the code ?

thanks

Silvia, Frank I am running a Time History analysis using ver. 1.7.3, am recording a lot of output signals and getting this error: WARNING - PathSeries::PathSeries() - could not open file Gmotion.txt If I reduce the number of output stations, or just take out the recorder command, it works fine sugge...

Silvia, I cannot recall if an input file with multiple points per line (like PEER format) can be sourced in without transforming it into a single point per line (column) input file with your procedures say, if this is my file -1.69164e-01 -1.72163e-01 -1.81138e-01 -1.95025e-01 -2.12332e-01 -2.31377e...

thanks, that really helped

hi all I am doing some parameter analyses, using different ground motions I want to load different motions (Motion1... MotionN) using different Scale Factors for each one of them. but I think I am missing some syntax rules on how to transform the Scale Factor string into a number (should I use the e...

Frank, Silvia

I am running OpenSees parallel
and it returns me this error:

PartitionedDomain::addElementalLoad - not yet implemented

any suggestion?

thanks
