How to apply pressure load in no. of cycles ?
How to apply pressure load in no. of cycles ?
(OP)
Hi all,
How can i apply a pressure load on a surface in no. of cycles ?
I have to use trapezoidal load form over 1 sec and it repeats for 700cysles at 1 Hz.
I can apply the load by using *Amplitude ((tabular method) for 1cycle as
*Amplitude, name=Amp-1
0, 0.1, 0.05, 1, 0.45, 1, 0.5, 0.1
1, 0.1
*Dsload, amplitude=Amp-1
<surface name>, P, 2e6
But I am wondering how can i apply the same load for 700 cycles at 1Hz.
Would please help me in this context?
Thanks in advance
Regards,
Krishna

If i use time=step time, then i should use 700steps if i understand correctly ?
@vumat721
I will look at my load to represent in fourier series..
Thanks !

you could create the repeating amplitude pretty easily in excel without too much worry about typos, then export it to a comma-separated-values (csv) file which you can copy-paste into your input file.
