I previosly worked with Comsol program but I didn't solve my problem..
I need to simulate compression test in a finite sample of 3d periodic structure.
problem is that one unit cell has 5000 mesh elements and I need approximatly 1000*1000*1000 unit cells (this for nanotechnology purpuses) It causes to crash due to out of memory error..
Another way I went was using periodic boundary conditions and I succeded in unlimited case(infinite layer) but nevertheless in life I have finite sample(~1000*1000*1000) with free constrains on the edges. Therefore I have big losses in poissons expand of whole sample.
The question is can Ansys solve my problem or not?
thx in advance,
Are you saying you want to generate a model with 5 trillion cells?
No, no software on the planet can handle that.
We have done Billion cell models, even close to 2 Billion if you have the hardware (coincedentally, the hardware to run it costs about a billion dollars. :eek:)
You need to reduce your model some how...
There are lots of ways including sub-modeling, symmetry, etc.
