    WinIGS - grounding software

    Yes 10^-12. The 44kV fault is 5.5kA in my model. I'm getting no fault current into the grid from what I can tell, the earth current is also coming out as zero, my GPR on the node that the grid is connected to is always 0, on the node that is on the secondary side I get a GPR up around 16 kV if...

    WinIGS - grounding software

    Kiribanda, yes you can model the soil as a 2 layer model, it also has options to accept test results, such as the weener method. umrpwr, I have sent Sakis a few questions, he has responded so far, I was just hoping to find some additional resources, such as a user group or similar, I am not...

    Linking problems with subroutines

    Hi, I am still having problems, I am getting the following error messege: LINK : fatal error LNK1104: cannot open file "LIBIFCOREMD.LIB" ABAQUS Error: Problem during linking - ABAQUS/Standard User Subroutines. This error may be due to a mismatch in the ABAQUS user subroutine arguments...

    Linking problems with subroutines

    I have installed visual c++ and intel fortran but abaqus fails to recognize either one when I run the abaqus verification, is there some sort of trick here besides installing these programs? For reference I have tried visual studio c++ 2005 express, and 2008 beta, along with a trial version of...

    Using test data to find elastic parameters

    I was just using that as a simple example, I am actually using a hyperelastic model and wanted to compare results between defining parameters for the polynominal strain energy model, (c01,c10,c02,c11,c20), versus using nominal stress-strain data with the TEST DATA INPUT card, so given the input...

    How to print strain invariants?

    Can you print the strain invariants, I1,I2,J in the dat file? If so what is the appropiate notation? I can't seem to find anything in the documentation about this.

    Using test data to find elastic parameters

    I would like to know if it is possible to see what ABAQUS uses for material properties when I use test data to define the material. For exmaple let's say that I input some uniaxial test data for a linear elastic material how would I see what ABAQUS chooses to use for the poisson's ratio and...

    Using test data in hyperelastic model to get the parameters

    Hi, I am wondering if it is possible to obtain the elastic paramters from a model when using test data to define the paramters in the first place? For example say I have some stress-strain data, I use this with the polynominal model for N=2, and I want to know what ABAQUS then decides to use...

    How to model BIphasic materials

    How can this be done in ABAQUS? (I am trying to model a soft tissue indentation test). Thanks.

    Defining coordinate points from an image

    Hi I am trying to define x,y coordinates from an image. I would like to be able to just click a series of points on the image (after displaying it) and have the x,y coordinates recorded from each click automatically. Is there a way to do this? My end goal is semi automatic segmentation of an...

    Is it possible to generate mesh from picture?

    I am trying to generate a mesh based on a photograph of a slice of an object, where the thickness of the slice is known. I am currently generating the mesh in matlab, creating input files for ABAQUS to use, however if possible I would like to just do it all in ABAQUS, I don't think it is...

    Possible to generate input file from CAE?

    doubleje, I am using the following command to run abaqus in matlab, (windows system): !abaqus job=jobname interactive where jobname is the name of the input file without the file extension

    Breaking a data file up

    Hi, I am trying to read a file and extract only a section of it, for example if the read file was the text below I would only want to extract the text between "test1" and end_test", which would be "this is a test to see if i can get these words from this file." My goal is to take only the...

    Possible to generate input file from CAE?

    Is it possible to generate input files from CAE? If so how? Also I am using Matlab with Abaqus, I know how to run an input file in Matlab but I do not know how to view the results, except for manually going to the directory and opening the file in Abaqus.

    Completely new to Abaqus...indentation problem

    I am trying to create a soft tisse indentation problem, I want to use a script and eventually use matlab to invoke the script and diplay the results, I have 3 questions: 1. If I build a model in the the ABAQUS CAE can I somehow transfer the model and all its properties into a script to build...
