    problem *INITIAL CONDITIONS, TYPE=STRESS

    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...

    fortran compiler

    hi, can anybody tell me how to setup a fortran compiler in abaqus. I installed force 2.0 a freeware compiler and I think it "linked" automatically to abaqus. still I get following error when running an analysis: - problem during user subroutine compilation - df.exe not found in PATH...

    connectors - foundation

    dear all, my aim is to investigate steel piles in soil. Hence, I need to model the interaction between soil and shell elements. there are the following possibilities: - with *foundation - with springs - with connectors 1. Which method is recommendable? 2. If I e.g. have a planar shell plate...

    element choice - contact, high stresses

    Dear all, I am modelling a structure including regions of high stresses and strains (weld, notch)and al lot of contact (3 plates on top of each other - all in contact). The investigated model is a steel connection with bolts. It is modelled 3D. I have modelled the problem with various element...

    submodelling - finer mesh

    hi, I have encountered a problem with a submodel. the submodel works out fine (3D model - elements (hex)). but sometimes while using a fine mesh (not really fine - it should be calculated within a minute) the analysis is terminated and there aren´t any comments in .dat or .msg or whatever why it...

    Buckling behaviuor of pipe piles

    hi, I have a research project on the buckling behaviuor of pipe piles (combined walls). My question is how to model the pipe-soil contact in an easy and efficiant way in ABAQUS (FEM). Thinking about Winkler spring.. that at first leads me to the asumption of the winkler spring subgrade modulus...

    local coordinate system

    how can i define a local coordinate system that is allowed to move independently from the rest? for example defining boundary conditions for some nodes in a CSYS that moves along with the deformation?
