Hello guys,
I would like to know if the application of a pressure in case of dynamic analysis(Transient direct) has to be done in this way.
I have to apply a pressure on my component, to divide on 4 different areas of the component (the areas has the same value). This pressure is time variable, in particular is equal to 0 MPa at the time t=0 s and is equal to -3.648 MPa at the time t=2s.
I created a load collector (named “Pressure”), I highlighted the elements on which to apply the pressure (and so I defined the 4 areas on which to apply the pressure), I choose a load type PLOAD4 and I defined the magnitude of the pressure (to the value -3.648/4= -0.912).
I created a load collector(named “Interval”) with Card Image TSTEP, and since that I would like to divide my time interval of 2 seconds in 5 steps of 0,4s I set N=5 and DT=0,4s.
I created a load collector (named “transient') with Card Image TABLED1, I set Data:
0 s 0 MPa
0.4 s -0.1824 MPa
0.8 s -0.3648 MPa
1.2 s -0.5472 MPa
1.6 s -0.7296 MPa
2 s -0.912 MPa
I created a load collector (named “Study”)with Card Image TLOAD1 setting EXCITEID=Pressure and TID=transient
I created a loadstep with Analysis type=Transient(direct). I set Dload=Study and TSTEP=Interval
I have a first question, since that I have 4 areas to load, the magnitude of “Pressure” to set has to be equal to - 0.912 MPa or to (-0.912*4= -3.648) MPa?
Moreover I would know if also the values of the pressure in the Data have to be multiplied for 4 or to be left as written previously.
The second question is the following, is this the right way to set the problem in Hypermesh?
Thank you for your support!
