envelope value of absolute acceleration

[saharnaz]

hi every body
how we can get the maximum of absolute acceleration with envelope node recorder?
when i use envelope node recorder out put is relative acceleration not absolute acceleration.

You need to add the time series to your recorder definitions, e.g.:

recorder Node -file acceleration.out -time -timeSeries 1 0 -nodeRange 1 4275 -dof 1 2 accel

The 1 and 0 after timeSeries indicate that time series should be added to 1st DOF and not 2nd DOF.

Bests,
