free autoCAD software compatible with Abaqus ?

Dear all,

 I need a free autoCAD software to model the complex 3D geometry of human brain.  It is desirable that this software should generate output files readable to Abaqus/CAE for mesh generation.  I wonder whether these is such a software available.  An alternative way is to handle the geometrical modeling myself but I need to know the details of the file format used by Abaqus/CAE.  Does anyone have a clue?

Thank you very much!

DLOAD subroutine

Submitted by cgouder on

Dear friends .

                   This is the first time i am using abaqus for analysis. I am doing a moving load analysis of a bridge .I have planned to apply a  distributed load and vary the profile using DLOAD . Do you think its a good idea ?. Can anybody send me an example file of DLOAD.

Thanks and Regards

Simulate moving laser beam on a plate in ANSYS

Submitted by daltoy3 on

Hi everyone!

I've been trying ansys for a few weeks but in vain. I'm trying to inject a heat source(laser) on a 2D rect plate. I'm not sure on the corrct way to add the boundary conditions. This is what I do:

1. assuming room temp so i added 298K to the bottom, left and right using define loads >add_temp>lines

2.next i inject a heat source say 1000K using define loads>add_temp_on nodes to a few surface center nodes (meaning the top surface still have undefine boundary conditions)  

modeling cohesive element

Submitted by sandra on

hello,

 i am modelling a concrete beam with FRP bonded to beam with the adhesive. i hav tried to simulate adhesive using cohesive element Abaqus(from manual) for the past 2 months, but am getting missing  property definition for those elements.I am not sure the procedure I hav followed is correct, so please send me the procedure for modelling cohesive element and the contact between the adherent faces.

waiting for the  reply

 

Software/codes for atomistic/continuum coupling multiscale materials modeling

Submitted by Shuozhi Xu on

There exist some software/codes for atomistic/continuum coupling multiscale materials modeling methods (in alphabetical order):

1. AtC, atomistic-to-continuum coupling, included in LAMMPS

2. BDM, bridging domain method, included in LibMultiScale

3. MMM, multiresolution multiscale mechanics method
