Hi Part of my code utilizes csv package (package require csv) in OpenSees which should be related to tcl. It is run fine on my computer but on stampede whether I use OpenSees OR OpenSeesMP , it does not run and it says : can't find package csv I was wondering how this can be resolved ? Thanks RG

Thanks Frank ! To those whom would be using OpenSeesMP on stampede , you may use something like this as your batch script to be executed using "sbatch" command on the login node (scratch preferably) #!/bin/bash #SBATCH -J TRUSS # job name #SBATCH -o TRUSS.o%j # output and error file name (...

I am new to stampede ! I have borrowed this script from one of Frank's presentations ! When I am running this on stampede through batch submission I am getting this error : /home1/00477/tg457427/bin/OpenSeesMP: error while loading shared libraries: libpetsc.so.3.6: cannot open shared object file: No...

Thanks , i think i asked my questions not quite properly . I meant exactly what u mentioned as it can be seen in the peace of code I have shared above . However, i meant in order to set the horizontal translations, to move together using equalDOF since i have no joint node separately defined as thos...

Hi I was wondering how can I constrain the dof1 of the nodes in each floor in a frame where I use joint2D elements for joints ? Since the central nodes are generated automatically by joint2D then when I use equalDOF command , it gets me a convergence error. I use this for that purpose : # start from...

Hello Assume we have a set of parameters like set LA1 3 set LA2 4 . . . set LA10 10 and we wanna call them in , into a script like: set {for i 1} {$i <=10 } {incr i } { set b($i) [expr $LA$i+1] } [expr $LA$i+1] does not work , any suggestions that i can call in LA1, LA2,... LA10 automatically into m...

Hi I have a 3D reinforced concrete model . I wanna add Shear/Axial springs on top of each column (with fiber section) to model shear/axial degradation. Should I just define ONE additional node besides the join node and connect those 2 nodes using a zerolength element? Then I can add 3 different mate...

Hi I am running numerous dynamic analyses and I am recording various Engineering Demand Parameters (EDPs). In order to save my memory space I am willing to just select the peaks and possibly the end values for various EDPs and record them in a text file and then get rid of the other data. Is there a...

I got this error when I ran a simple example ( Example.tcl) on Hoffman cluster at UCLA , Can you help me find out what's going on? Num Processors: 4Num Processors: 4Num Processors: 4 Num Processors: 4 while executing "system Mumps" (file "Example.tcl" line 43) Process Terminating...

Hello I am going to parallelize the code for my 3D-8-story RC building using OpenSeesMP There is going to be a vast number of parametric studies in which input parameters would be taken into account as Probability Distribution Function (pdf) Besides, record-to-record uncertainty in ground motion wou...

Hi I am getting this massage when I am trying to do dynamic analysis on my 8-story concrete frame building which is modeled in 3D. "couldn't read file "ReadNGAFile.tcl": too many open files" How can I fix this problem ?? here are my recorder commands given below ; When I limit ''...

Hi I have always used opensees on windows ! Recently I have become a mac user . I have opensees in the same directory as my files But when I put source test.tcl , i get this error "couldn't read file "test.tcl": no such file or directory" should I use different command in mac?

Hi I use fiber section to simulate flexural behavior in columns in a 3D frame. I also attached axial and shear limit state material including axial and shear limit curve at the top of each column using zero length elements. Now I would like to record the shear and axial responses in column and plot ...

What is the best element , material model or strategy to model concrete shear wall in a 3D fashion ?

Your suggestions would be much appreciated.
