Yet another question on MATLAB and ABAQUS

[SomethingPunny]

I've sifted through quite a few threads on interfacing MATLAB with ABAQUS and still haven't managed to find a useable answer. I'm an absolute beginner with ABAQUS, so bear with me.

Problem: I've defined the geometry of a problem in some arrays in MATLAB (an array of nodal coordinates and an array of element connectivity). Now I need to export this information to ABAQUS (from what I've gathered, in the form of an *.imp file). Everything I've read is either firmly in the "Bah! It can't be done" camp or something along the lines of "just use fprintf".

Bottom Line: So assuming fprintf will get me somewhere, how do I get these two arrays into a file format that ABAQUS can actually use.

Thanks

You should familiarize yourself with the format of the Abaqus INP file, in particular the *Node and *Element keywords. Sorry to sound like all the other threads but once you have the correct syntaxsomething like)
"
*Node
Node Label, X Coord, Y Coord, Z Coord
....
*Element,Type=CPE4R
Element Label, Node Label 1, Node Label 2, Node Label 3, Node Label 4
....
"
generating the INP file is simply a matter of using Matlab print statements to write out your nodal co-ordinates and element connectivity as required.

In the same line;

try to create a really simple model in CAE. (yes first you have to familiarize with the CAE, and design your model as basic user)

then solve it
Abaqus will create an inp file, then you can check it out ad understand more about the code. (Actually I also have to do that work : ))

then force matlab to writte something like that.

good luck.

here seems to be a simple example
