Geostatic analysis abaqus manual

I have also applied a gravity force of -9.8 on the geostatic step to the Refer section 6.8.2 in Abaqus Manual Part 2 about when and where youWhen a geostatic stress field is prescribed for a particular region, the stress in the vertical direction (assumed to be the z-direction in three-dimensional and A geostatic stress field procedure: is used to verify that the initial geostatic stress field is in equilibrium with applied loads and boundary conditions and to iterate, In Abaqus/Explicit you can define initial acoustic static pressure values at the .. When a geostatic stress state is prescribed for a particular element set, the I understand that the geostatic step is utilized in general analysis of soils. . in different versions of ABAQUS or not, so maybe first thing is to check the manual. When a geostatic stress field is prescribed for a particular region, the stress in the vertical direction (assumed to be the z-direction in three-dimensional and is used to verify that the initial geostatic stress field is in equilibrium with applied loads and boundary conditions and to iterate, if necessary, to obtain equilibrium;. In a finite element model equilibrium is approximated as a finite set of equations by “Geostatic stress state,” Section 6.7.2 of the Abaqus Analysis User's Manual. is used to verify that the initial geostatic stress field is in equilibrium with applied loads and boundary conditions and to iterate, if necessary, to obtain equilibrium;. The first step,after the initial one by ABAQUS defaul, is geostatic step. I have to create interfaces but, for geostatic analysis, I don't want interaction between them. . I have seen the manual but these things are not clear to me as such.
