    Local reference system

    I need to create a local reference system applied to a two elements beam rigid body. I tried the command *TRANSFORM but the user manual writes as follows: “The transformed coordinate reference systeme system is always a set of fixed Cartesian axes at a node (even for cylindrical or spherical...

    Boundary Condition

    Hi, In my model I have a part that is a beam meshed using pipe elemnt. As showed by the figure in attachement I need to apply a boundary condition that restraint the movement of the node N2 in the transversal direction with respect to the beam axis (i.e. along the axis 2'). Global axes in my...

    abaqus and numpy

    hi guys, regarding the information given in thread 799-196031 I'd like to know if I need to download the activestate or Enthought distribution or it's enough to dowload the packages following the links given, for example, at the web site http://www.scipy.org many thanks

    Python and arrays

    Hy guys, I need an help on how to manipulate arrays in python using the module Numeric or array. Consider the following array a a = reshape(arange(9),(3,3)) >>> print a [[0 1 2] [3 4 5] [6 7 8]] ok, now how is it possible (any command?) to add a new row let say [9,10,11] to the array a in...

    python - how to create a node set

    Hi guys, I'm reading the obd file to postprocess an analysis. The point is that, in my python routine, I would like to create a node set that I did not create in the preprocessing. In this way it is much easier when I extract the results from the fieldOutput. How is it possible? thanks in...

    user subroutine

    Hi guys, I want to write a simple subroutine that gets the coordinates of a node (i.e. 10600, see attached file) and, at the moment, writes them in a text file. Generally I start with simple exercise for understanding how to use, in this case, the function GETVRN. My question is, as far as I...

    Problem with DOF constraint

    Hi guys, I have some difficulties to constraint the displacement DOF of nodes 1 and 2 (see the attached file) to the correspondent nodes 3 e 4 (in the figure the rigid body RB3D2 is shifted in order to make the nodes to be visible, actually the nodes are superimposed i.e. have the same...

    Problem with rotations output field

    Hi guys, I had some problems in understanding the rotation output field in the viewer. Therefore I gave a look to the doc., in particular I'm referring to the user manual section "1.2.2 Conventions". At the end of the first example (i.e. 60 degrees about z-axis, 90 degrees about beam axis and...

    GUI & data plotting

    Hi guys, I have to plot a serie of data (x,y) that are read from a text file. How can is it possible to store the data in a variable in the workspace in order to make it possible to access/process the data after each action (for example after pushing a button etc. etc.) without reading the txt...

    User Subroutine

    Hi guys, I'd like to specify the maximum time increment of a step while the step is running. I mean, I'd like to implement a subroutine that after a step increment is finished, some outputs are extracted from the fil, then I perform some calculation with this outputs then on the basis of the...

    Abaqus & Matlab

    Hi guys, is it possible to write a matlab subroutine that excute as follows: 1- run a job 2- wait untill the analysis is ended 3- call a fortran postprocessing subroutine compiled with abaqus thanks in advance for any advice

    Adaptivity Mesh

    Hi guys, I'm quite new with the command *ADAPTATIVE MESH and I'm trying to improve my model with this option that is given in ABAQUS. When I just added this line *ADAPTIVE MESH, ELSET=SOIL_ELE, FREQUENCY=1 to my input file, the analysis datacheck stopped with the following error: ***ERROR...

    Deformed shape

    Hi, I already know that with abaqus viewer is possible to superimpose a deformed plot with an indeformed plot, but is it possible to superimpose two deformed shape referring to a two different load increment? Thanks Bye

    Soil analysis example

    Hi guys, where can I find, in the net, some simple example, I mean input file, to better understand how to model soil (sand and clay) and to work with it. The question seams to be stupid but I'm not used with this kind of problem as I'm mechanical eng. and the examples on abaqus doc. is not very...

    Beam component in contact with rigid surface

    Hi, I'm trying to simulate a process that is close to drawing. The model has two parts: the first is a long rectilinear beam (meshed with beam elements), the second is a rigid surface with very irregular shape (meshed as analytical rigid surface). This is essentially a 2D problem. The beam...

    Necking analysis

    Hi all, I'd like to know if someone have ever tried to simulated FEM analyses with Abaqus far beyond elstic limit. I mean, in the analyses I'm trying to simulate the phenomenon of necking in particular my question is this: assuming a material stress-strain curve with a uniform elongation of 10%...

    pressure load and abaqus viewer

    Hi everybody, I need to know if it is possibile to show pressure loads applied on solid or shell element once the run is completed. I mean, I wrote the input file directly through a text editor. The model is based on solid element (C3D8) and I've applied a pressure load on the faces of some...

    Abaqus and Standard Memory usage

    Hi, I have some problem with the ram memory installed in my pc and how abaqus use it. Recently I've upgraded the ram of my pc from 2Gb to 4Gb. The first problem is that my os (windows 2000) do not recognise all the memory but only 3.2Gb. When turning on the computer I entered the set up of the...

    How to use array with Python

    I'm trying to store some data with Python into a two dimensional array and I have some problems with the use of the List object indexes. Let consider for exaple the following list a=[[1,2,3],[4,5,6],[7,8,9]]. Ok, after this command, if you type a[0][0] the result is 1, if you type a[0][:]...
