problem *INITIAL CONDITIONS, TYPE=STRESS

[abaqusshell]

Hi,
does anybody have experience with the keyword (example):

*INITIAL CONDITIONS, TYPE=STRESS, GEOSTATIC
101, -100., 1.0, -100., 0.0, 1.0

for a CPE4 element.
I do not know how to read it. For example if I want to implement stresses into a single 3D element like this I would have wrote something like:

*INITIAL CONDITIONS, TYPE=STRESS, GEOSTATIC
element, -1, -1, -1

because of the 3 degrees of freedom for each node..
but it seems im not right.
can anybody explain how the inbitial conditions work?
thanks,
Anton

Check the example problem on fluid sloshing. I believe you want to specify the direction in which the gravity is acting - so you may want to specify 0,-1,0 instead of -1,-1,-1.

Like I said though, look into the documentation for the fluid sloshing example. They used /Explicit and adaptive meshing for this one, but they had to preload the fluid using the geostatic initial conditions.
