hello,silvia.can you give me a explaination about that why we get a absolute same displacement records of different node of one story when i do as follow to input the ground motion record

set dispSeries1 "Series -dt $dt -filePath $outFile -factor 1"
set dispSeries2 "Series -dt $dt -filePath $outFile -factor 1.5"
pattern MultipleSupport 2 {
groundMotion 1 Plain -disp $dispSeries1
groundMotion 2 Plain -disp $dispSeries2
#the 7th storey(25,26,27,28 are the 7th storey node)
imposedMotion 28 1 1
imposedMotion 27 1 1
imposedMotion 26 1 1
imposedMotion 25 1 1
#the 6the storey (21 22 23 24 )
imposedMotion 24 1 2
imposedMotion 23 1 2
imposedMotion 22 1 2
imposedMotion 21 1 2

and when i adjust the factor of node 21,22,23,25,26,27with zero,the result level displacement of that node are zero too.

because you are controlling the displacements and you are setting them to zero.

Can you please tell me if the version 2 is the best version to use? the archived version says "Beta" when I open it.
I appreciate your help dz@gobav.com http://gobav.com/ for reply notification, or is it automatic?
Thank You
