import 3D model from Matlab version 7.1.0.183 (R14) Service Pack 3 to abaqus 6.7 EFI

Hi,

I read up the importing details for abaqus. I cant find any information regarding whether 3D model from Matlab is able to import into abaqus. I have the mathematical equation for the model. I need the 3D surface. Is it possible to import? Please advise. Thanks.

You should be able to import any external material model into ABAQUS if you convert the model geometry into the required format.

As I mentioned in another post, you will need to define the coordinates of all nodes, and then you will need to create all elements. I suggest that you read the user's manuals for how to use the *Node and *Element commands.

Dear all,

I need HELP !!!
I'm new in Abaqus and I'd like to import the
mesh(coastline)to abaqus that I generated in matlab. But
abaqus recognize just sat ,igs-stp-dxf format .In matlab
there isn't function that would export to this type of formats.

Thanks ;)

I do not know of any function of Toolbox that enables Matlab to directly export in to Abaqus. You can, however, without too much effort save your mesh information (nodal coordinates and connectivity) in to an Abaqus inp-file that can be read by Abaqus/CAE.

Dear Jorgen

Thank you !!! you told about an inp . file.......:oops: do i have to save the m. file as inp file? can you give me an example for an inp file?

thanks again!!

Your m-file has to stay an m-file. The m-file can write the inp-file using "fopen", "fprintf", and "fclose" commands. You should read the abaqus manuals about the required format for the inp-file.

There is a 3d party toolbox called IMAT+ to communicate between abaqus and Matlab,but not freely available, searc in google imat from a.t.a engineering i quess
