Two instances of Kangaroo

I dont' know if this is the wrong way but it seems to be working! (very draft, need a lot of depuration and probably a youger brain!!)

here is a link of my simulation first attemp

http://vimeo.com/71659439

One instance of kangaroo output (rod bend resistance) is feeding another instance of kangaroo solving a mesh relaxation for canopy's membrane.

It's still incomplete as I need the feedback of fabric forces as input forces for the rood.

but a circular reference of iterations would not allow me to do this.

I'm trying to get a simulation of the phisics between the two structures levels, rods and membrane interacting the bend resistance o the roods and the final form of the membrane limiting the rods to get straight.

I apologize for the very messy wired diagram ..... I'm always a newbie and kangaroo is excellent enough to let me do things even in a wrong or indirect way.

Help and suggestions are always wellcome!

attached there are images of canvas and model

Many thanks in advance for any suggestion or idea.

Hi Alejandro,

There's no need for multiple instances of Kangaroo here - different objects such as the membrane and rods can be combined into a single simulation. As long as the vertices of the objects coincide they will be automatically joined together.

To actually output the geometry separately you can entwine the data paths and split after output

See the attached file for a simple example

Thanks a lot, Daniel... ..... Feeling such a newbbie again... ;-)

I'll start over with this in mind. Just another two questions (I may say this would not be my last questions for sure): what kind of units are used in Kangaroo?

Where can I find reactions for anchor points or anchor springs or simple springs...?

I'll post results of my new simulation here, as soon as I get it working again.

Regards

Ale

Daniel: Forget about the questions !!

I found your post , and is enough for now! ->

I should have searched before asking!

Thanks anyway!!
