FEM CODE MATLAB 2D

FEM CODE MATLAB 2D

FEM CODE MATLAB 2D

(OP)
Hi,

i need a matlab code for a 2D-beam problem using the fem. i have to modify it, but need a basic code to start with.
please help me. it is very urgent. thanks.

RE: FEM CODE MATLAB 2D

(OP)
No,it is not for school. i'm doing a research at my working place.i Nneed a basic code to develop it with new features, which fits in to the research.

RE: FEM CODE MATLAB 2D

I think I might have a matlab based FEM solver with beam elements. I can send some of the code, but I'm just curious as to why you would want it. Does your place of employment not have commercial code? You can even do simple beam FEM problems by hand if necessary.

RE: FEM CODE MATLAB 2D

(OP)
Thanks for the help. Openfem seems to be to complicated.

I need just 2D FEM solver, which i want to develop for non-linear problems.

My company usually doesnt work with fem. thats why we have no commercial programms. It is just a research, to find out if fem fits to our necessarys.

@CSK62

I would be very grateful if you help me.Thanks.

RE: FEM CODE MATLAB 2D

Hi

Another approach could be to evaluate an existing commercial code. Just to see if it fits your needs.

Then you don't have to 'invent' something again.

Good luck

The problem is that such commercial codes are not open or modifiable. Thats why our idea was to start with a easy 2D Code ( linear or nonlinear) und develop it. It is just an experiment, if it would work oder not.
I am a beginner in FEM so that is very difficult for me to wrote a complete new code. It would be very helpful if someone have a ready code.

RE: FEM CODE MATLAB 2D

Hi again

Is your problem something that the available commercial codes are unable to handle?

I am just being curious smile.

RE: FEM CODE MATLAB 2D

Seems to me that anything that the OP is attempting to code up, given his current level of expertise, is unlikely to not be included in the functionality of a commercial FEA package.

Also, it seems to me that if the OP is looking to determine the applicability of a commercial FEA for his application, that he should put together a test for his candidates to demo. This would seem to be a better approach than to attempt to code up something from scratch, since it's most likely that one would be spending time debugging programming errors rather than evaluating performance. Moreover, the likelihood is that a commercial FEA package is optimized for throughput, while anything create, ad hoc, will not be.

RE: FEM CODE MATLAB 2D

2D FEM for beam elements. I think this code was developed by some students at an unnamed university in Ithaca, NY frosty, so I don't know if copyrights apply. Use at own risk, but I think you should be fine, its not really novel.

As for manipulation of the base code, I'm not really sure what you want to expand on, but good luck. If anything obvious is missing let me know.

Thanks to everybody, i think i have the answer.
