it is a sample recorder command that I used in my scripts and works well.

recorder Node -file rott.out -dT 0.02 -time -node 3 -dof 6 disp

In this line the z axes rotation of node 3 with 0.02s time increment will be recorded in file rott.out

I am using a script to run a parameter study on a model. I was using a transient analysis with constant time steps in windows base system. 1-because of small time increment in transient analysis the output files are very large. is there any way to increase recorders time step increment to reduce the...

for runing this batch Opensees.exe win version has been used.

dear Sylvia model.tcl file: ******************************** model BasicBuilder -ndm 3 -ndf 6 set h 300.0; set by 1800.0; set bx 2000.0; node 1 [expr -$bx/2] 0 [expr $h] node 2 [expr $bx/2] 0 [expr $h] node 4 [expr -$bx/2] 0 0 node 5 [expr $bx/2] 0 0 node 6 0 0 0 node 7 0 [expr -$by/2] [expr $h] nod...

I think batch process will stop when it arive to eigen command

I shortened the script. this script call model.tcl that for each analysis generate nodes, elements, masses and constraints. ###Run.tcl Start wipe # Define earthquake excitation # ---------------------------- foreach pga {0.05 0.1 0.15 0.25 0.35 0.45 0.55 0.7} { set pg [expr int($pga*100)] set fac8 [...

I have this problem too. I use opensees batch analysis. I use foreach command. On each loop i analysis one earthquake and then change Pga and run the analysis again. but always after 3 or 4 analysis i got this message " BandArpakSolver::Noshift could be applied during inplicit Arnoldi update,tr...
