Fatigue analysis with oscillating pressure

mabefa

Hi,

I have a component in HyperMesh in which I have imported a distribution of pressure with a csv file in which there are the coordinates of the points where the pressure is applied, and for each point there's the value of the pressure. I also have two other csv files where there's the value of an oscillating pressure for each point: in one I have the real part of this oscillating pressure, and in the other the immaginary part acting on each point. With this two files I created a loadcollector with card image DLOAD.

Now I would like to do a fatigue analysis with this DLOAD.

Is it possible to do it? If yes how can I set the analysis with this type of loadcollector?

Hi @mabefa

 

Yes, you can run a Fatigue analysis with transient subcase. During Transient Fatigue Analysis, the load-time history input is not required, as it is calculated internally during Transient Analysis.

 

Refer Transient load case in FATLOAD>> LCID and leave the TID blank.
