    Transferring the mesh to an orphan one

    It seems that some boundary conditions can be only prescribed on mesh nodes ,e.g, when one wants to apply hydrostatic pore pressure on a face of a dam one has to calculate (manually) the pressure on each node on that face and then put the number as a boundary condition on that node. Do you guys...

    Material Properties Change

    I have two steps to analyze a sample of frozen rock : Heat transfer and Static or Soils Step: upon subjecting it to heat transfer analysis the permaebility, strength , and other rock parameters will change. How can I account for that in the Static (SOILS) Step. (PLease not I am not interested...

    Applying Pore Pressure as B.C

    I want to apply pore pressure BC or hydrostatic pore pressure BC on a side face (or in fact on only part of it). It seems that i should calcuate the hydrostatic pressure at each node of that side and then apply it on that node. This is a very tedious way particulrly if one has many nodes on...

    setting-up colours based on different sets

    I just want to change up the set-up of colours based on different Sets . I looked around 20m in the documentations on line but without finding how to do so. Sorry from ABAQUS experts if the question is simple

    Slope Stability Equilibrium and Stress states with ABAQUS

    I am wondering if any of you has conducted slope stability analysis with ABAQUS. Finite element is powerfull tool for observing Slope stability behavior with time. The Maximum contour of Mises Stress can be considered as mark of the slip surface location while FOS is computed by a criterion...

    Stand-Alone Sketch and Materials assignment

    1-I am not clear with the manual regarding what is the use of Stand-Alone Sketch:e.g how it is incorporated into the part or Assembly module. 2-When I want to assign different materials to a specific part or assembly I just partition them and then assign sets for these partitions and then...

    On shear band and homogeneous stress

    I am modelling triaxial compression test with one element (quadratic).One expects to get homogeneous stress state, but why I am getting nonhomogeneous stresses ( hardening at top nodes and softening at the middle ones ). Also when plotting the Mises countors I see discontinuity at the middles...

    Creating the model of an input (text file)

    I have an input ABAQUS file (text file).. is there any way to get the CAE ABAQUS model of this file without re-creating the model of this file Thanks

    Obtaining second order of work

    I am willing to get the following output : Second order of Work that is multiplication of stress and strain. Such operation seems invalid in ABAQUS How can i do that .? Thanks

    Geostatic step and Initial Stress

    Geostatic Step The goal of this step is to make sure that the system under analysis is under equlibrium state prior to analyzing it under any external effect.Prior to external effect, ususlly a system is subject to its gravity load and one in this step has to describe intial stress condition...

    Use of moisture content test results

    Usually in geotechnical reports we conduct moisture contents an samples across the investigated depth and evaluate these numbers in parallel with the results of Atterberg's limit and hence we can know the existing state of the soil; e.g, about plastic limit (PL), lower than PL ,at liquid limit...

    Visulaizing two models in the same screen

    Anyone knows how the results of two different Jobs under the same model can be visualized in the same screen Thanks

    Implementing user subroutine into ABAQUS

    I am willing to run my analysis with a UVARM subroutine ( I have already got the text file of this subrotine). How can I do that? I also think that I should add some associated instructions to the Input file and Output request Should that addition be done through Edit Keyword Thanks

    Getting Stresses at Nodes in the

    In the Visualization Module, there is Field Output under Result. As shown in this Field Output window the Stresses will be calcualted at the Integration Points while Displacements at Nodes. No how can one get the stresses to at Nodes so that this can appear in this window Thanks

    Contour lines Visualization

    A is a field output, B is another field output. As we know, the results for each can be displayed in a contour mode (visualization). Now I do not know how to display the contours line of the ratio A/B. Thanks for help

    PLastic Soil Bulk Density measurement in lab

    Hi I do not know how reliable it is to get the bulk density of clayey plastic soil from bulk samples in the lab. Any special recommendations about that. Thanks

    Displaying yield and failure surfaces

    Hi Is there any way where one can display the yield surfaces and/or failure surface. Thanks

    ABAQUS_triaxial test

    Hi I am using ABAQUS to simulate undrained triaxial test (strain/displacement control)on soils. I do not know if using two steps only : GEOSTATIC step followed by SOIL (consolidation) step which spans over short time (say 1 sec) and at which the prescribed displacemnet is applaied is...
