Hello.
I'm working on finite element analysis..

I do have tons of references/literature discussing about the algorithm and all
but i think i don't have enough time to write the code.. i only have a week to complete my ugrad final project.
Besides it's been a long time since the last time i do matlab coding.

I prefer the unstructured mesh, but in this kind of situation i wouldnt bother too much about that.

So, if anyone.. please let me know
Thanks.

You should probably check first with your project advisor if he or she is
okay with you using someone else's code for your mesh generation.

I have search for quadrilateral mesh generator in Matlab and I have found none. My solution is to use another software that can export the mesh in text file and working from that.

It may prove inspiring:

Can it handle quadrilateral mesh? It seems it can only generate triangular one.

There is only triangle mesh, but idea is simple (details in: http://math.mit.edu/~persson/mesh/persson04mesh.pdf), and could be expand to simple quadrilateral mesh.

Thanks, but as OP, I don't have time to work on meshing engine, expand idea, etc... Writing a decent mesh generator can take a lot of time and I better leave the task for people who work on this topic.

i haven't asked, but i'm pretty sure he's okay with that..
he once showed me an example of final year project, and it was way simpler than mine, even to consider that the mesh generation isn't part my work

seems the most plausible solution
still hoping for the matlab code though..
