Hello,
I am modelling vibration of a generator atop a 10m deep layer of soil. I would like to, if possible, eliminate the initial phase from my analysis. My current phases are as follows:
Initial Phase (Phase 1)
To monitor the effects of phase 1 (which ultimately I don't care about but the program forces me to keep it), I have varied the ΣM_weight value from 0 to 30. It turns out this has no effect on the displacements or stresses. What then is the purpose of the intial phase? I understand it is to initialize stresses but how come it is having no impact on my results?
I have attached a copy of my project to this posting. Also are there any other good recommended forums for Plaxis2D program. Yeah Yeah there is always support, but its just not the same...
I am modelling vibration of a generator atop a 10m deep layer of soil. I would like to, if possible, eliminate the initial phase from my analysis. My current phases are as follows:
Initial Phase (Phase 1)
Calculation Type: Gravity Loading
ΣM_weight: Varies, this is the purpose of my question
Apply Time Dependent Load (Phase 2) Load Multiplier with Amp = 1, Phase = 0 deg and Frequency = 10 Hz.
Calculation Type: Dynamic
Dynamic Time Interval = 0.5 s
Let Vibrate (Phase 3)No loading, free vibration
Dynamic Time Interval = 0.5s
