ansys abilities
 

Hi all

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,
Alex

5,000,000,000,000?
 

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.
