Hello,
It seems that the stresses were in tension rather in compression. I have simulated a model (only soil with solid185 element) having 4 elements and applied gravity as well as inistate command as shown below, but the problem is the initial stresses are not being applied linearly with depth. I am trying to establish a geostatic stress field such as σxx=σzz= K0*σyy where K0=1.
Inistate Command:
inis,set,data,func
inis,set,dtyp,stre
inis,defi,all,,,,LINY,0,17651.97,0,17651.97,0,17651.97,0,0,0,0,0,0
