Abaqus Python : reading odb file for field frame data

Hi,

I am running a python script to do some post processing on Abaqus odb file. While running it on Abaqus/Explicite output file I found it was taking more than usual time. And after timing the run I got the surprise that the most time consuming thing what just to read the time value for each frame. I have the script below.

def main():

odb=openOdb('F:/Scripting/.../.../Example.odb')

Selection of element bsed on the location in abaqus using python script.

Hi
I'm facing problem while writing a script for a parametric study.
After changing the each parameter the model changes and and the loaction of the interested element changes based on those parameters.
Also the element number changes.
Is there any command in python script to choose the elements based on the location ? 

Thank you in advance

selecting suface nodes in orphan mesh by python script????

Choose a channel featured in the header of iMechanica: 

Hi,

    I have a 3D orphan mesh in abaqus and I need to select a group of nodes that belong to the orphan mesh and that would have been on a 3D surface of the parent solid before it was orphaned.

   I know how to do this in Abaqus/CAE, but I don't konw how to realize it using python scripts. If there is a method, just like using "findAt()" to select a surface by coordinates , to select all the nodes on a outer surface of the orphan mesh and to select all orphan elements?

Your preferences in scientific/engineering/numerical programming

Hello everyone,

I am working on a project related to helping the everyday researcher do his/her programming easier and faster.

I have done a fair amount of research work at OSU and have gotten a feel for the way they program on a daily basis, but realize that it could be and probably is drastically different on different parts of the planet. As such, I am here to ask the following questions (really, any opinion helps, so feel free to respond with whatever you want):

please help in debugging this

please tell me the errors in this programme please

Extracting boundary conditions from output database (odb) file using ABAQUS scripting

Hi,

I am familiar with abaqus python scripting to create odb files and to extract nodal data from an output database (odb) file in ABAQUS. I would like to know whether it is possible at all, to extract the boundary conditions from an odb file. I guess that the boundary conditions are not stored in an odb file. But I am not sure. Any help in this regard ??

Abaqus Script Manual/Tutorial

I have written a introduction manual/tutorial on Abaqus Scripting. I got some good feedback from my colleagues. Therefore, I would like to share the manual.The manual should give a short introduction (it will not take more than one hour) to Abaqus script in Python.

You can find the manual here:

Abaqus Script Manual

Via the same link you can also find more information on the connection between Matlab and Abaqus

Good luck!

Abaqus - evaluate stress at point (x, y, z)

Hi everyone,

I would like to evaluate the stress value (e.g  Mises) at a given point (x, y, z) within a 3D model. I cannot force this point to be a node. The problem is modeled with Element Type (C3D4).

Is there a built-in command I can issue in the input file of Abaqus to have Abaqus output the desired value to the output file?

Or, is there a python script I can use for this purpose?

Thank you,
-Ramin
