Can OpenFOAM do breaking glass simulations, like the shattering of the front window of a car?

Just curious, no need to go in details.

Yes, it can.

Don't worry, I won't tell details. Forget OpenFOAM for your arts stuff. Gimp or Photoshop is what you are looking for.

Cool, thx!

Right.

Hi,

ok. From reading your posts, I think, it is fair to say, that your interest are very widespread covering a lot of fields. So, for most of the artist stuff you will probably ask in this forum you might have a closer look at Blender rather than at OpenFOAM, because latter is a C++ library for CCM, not an artist tool .

Here some links as a start basis:

• http://www.blender.org/download/get-blender/
• http://blenderartists.org/
• http://www.blendernation.com/blender-artist-tutorials/

I plan to use this package for volume rendering purposes of vtk data (numerical results from OpenFOAM, gas-liquid flow). But there is a whole bench of further functionality.

The most interesting branch for me is the SimPhysics containing many physically based models:

• http://www.graphicall.org/builds/bui...on=show&id=903

Simply use some search engine or go through some video/animations portals to see its functionality. Have fun!

Hi Holger,

Thx for you suggestion, I have blender running on my computer and it is indeed the program to do particle animation and it is very "tweakable".

The only problem is that it doesn't solve electrohydrodynamic fluid problems, so in blender I'm stuck in the world of fantasy.

A few weeks ago I didn't have any notion of how OpenFOAM works and the fact that you need a serious background of engineering and maths before using this program.

Also my "Art-concept" isn't very well formulated and vague, so I need to rethink what I want to do with it ... and if it would ever be applicable to generate in OpenFOAM ... a typical "the more you know the less you know situation"

But this question of bend or break kept tickling me so I just had to ask.

best,

m.

Hi again,

well, you should have another look at Blender, especially at the SimPhysics Branch. For some flow simulations, for instance, the Lattice-Boltzman-Method (LBM) is used! So, SimPhysics is placed at the interface of scientific visualization and modeling on a physical meaningful basis.

Therefore, you might find what you search in this branch or at least have the possibility to add your stuff. Anyway, this is an OpenFOAM forum, so I will end with this hint here.

Hey Holger,

Thx for the hint I finally got it, when you specified the "Lattice-Boltzman-Method" and I did some wiki~ research.

And a bit more specific - Newtonian fluid: In common terms, this means the fluid continues to flow, regardless of the forces acting on it.

Well, I always thought everything in Blender was gravity-wise inflicted, not so apparently.

This is process would be the best of both worlds ... and the way to go.

great lead,

thx

Just a general suggestion: if some feature you need is missing in Blender, try to contact them on their IRC channel (#blendercoders is the channel name) on freenode or at the Blender Foundation. They are very open to suggestions, and you will find out they use much more physical models than (at least I) expected to generate their effects. If you want to contribute to the development of some missing functionality, you won't have difficulty, since I directly saw developers teach to new users to do that.

Blender users and developers also publish also a number of quite interesting papers,and a good number of researchers from various universities is involved in the development of efficient techniques.

To make it short: just contact them with your doubts
