I am guessing by the database you mean a file.cae.
If this is the case then you still need to use a cae license but not run cae with a GUI
To do this you can call the script in the working directory as follows
abaqus cae noGUI=script_name.py
You will also need some stuff at the top...
Hi,
Sorry, I think I wrote the wrong thing. If accessing the odb from within CAE one way is to use,
myOdb=session.openOdb(name='myOdb', path='C:/......')
then
myOdb.rootAssembly.instances[instanceName].sets[elementSetName].elements etc as discussed above.
Hi
Lets say that you have an element set defined in the assembly that contains all the elements that are associated with the node set you mentioned above. To access the connectivity for each of the elements in this element set you would loop over the elements as follows
for i in...

I guess you could loop though all of the elements that are associated with the nodeset to work out if the target node resides in the connectivity list for a particular element. If so, you could then work out what other nodes are connected to that target node based upon its position in...
Hi madhavi27,
I dont think it is possible to assign different material properties to the same part in different steps. For certain material properties a work around is to have a temperature dependent material property defined and change the temperature of the part in the different steps. The...
Hi mechsid
There are no special purpose programs for this transformation that i know of. You will have to write your own python code to do this. There are a few commercial programs that do generalised crack tip meshing such as Zencrack.

Hi mechsid
The best way I have found to do this is to 1st create a mesh part of the cracked plate and then write a python script to transform the node locations in the plate to those of the required cylindrical geometry.

Hi all,
My first question is in regards to NFORC. My basic understanding is that NFORC calculates the nodal forces within an element that can be attributed to the stresses within that element. If I have a surface that defines a section through a 3D body, can I sum these NFORC for all elements...

I have done this before. You need to apply contact to the opposing seam surfaces. Although the documentation seams suggests this is not possible it is, and it works. There is one difficulty. If you are using the fracture mechanic capabilities and therefore define a crack tip...

You could try to define a seam (Intereaction-Special-Crack ???). I know this functionality is avaiale in 6-7. In this case the mesher creates duplicate nodes along the seam such that the surfaces along the seam can seperate. In this way the rest of the model can be simply connected as...
Hi all,
I was wondering if anybody knows how to use excel to generate a file that can be used as avnode file for NREAD in Ansys V11. All formats I have tried (.csv etc) either fail or do not read the data correctly.

Thanks corus
I have discovered that a cross section can be defined in ABAQUS using *SECTION PRINT. The effective forces and moments across this section can then be output but not in an .odb, just in the .fil or .dat.
A work around is to define a sub-model with a submodel boundary at the...
Dear corus and brep
Thanks for your replies.
Corus, in response to your reply, I have a further couple of questions.
Firstly, when calculating the axial force I understand that it is the average of the axial stress times the area, but when working in regards to a finite element simulation...
Hi all,
I was wondering if anybody had any idea how to determine the effective axial force and bending moment that results from a solid cross sections stress distribtution. That is, say I have a cross section through either a p.strain p.stress or 3D simulation, and I would like to resolve the...
