Can i ask when are you planning to issue the new Kangaroo release? Thanks

Operations on Kangaroo data trees output from simulation geomtery, nodes
2 Replies
If multiple springs are used in a kangaroo model, they all force into one input. THere is also only one output for all these grouped elements. My challenge is Post-processing operations on there data…Continue

Apply a time history as a force, displacement, or acceleration to a node, base?
Anyone tried to apply excitation loads to nodes in a flexible Kangaroo structure to simulate behavior? Such as a sine wave load the center of a catenary cable. Or, perhaps an earthquake base…Continue

Array of breps along a curve

Is there a way to select a Brep Geometry, then have GH use that source to place it along a curve, at the GH-based division points, remaining true to the planarity of the line (i.e. orientating it's…Continue

Splitting up quads to triangles, using the points for Hydro, Wind?

Daniel Piker replied to Michael Roberts's discussion Operations on Kangaroo data trees output from simulation geomtery, nodes"Hi Michael,
While the force objects need to be flattened, the 'geometry' input doesn't. So you can use data trees for your different lists of elements here. The output geometry then keeps the same data structure, so they can be…"
Michael Roberts replied to Jon Mirtschin's discussion Models created with assistance of Geometry Gym in the group Geometry Gym BIM"Ultimately, and in the spirit of true integration, we are all seeking the all-inclusive BIM model that requires no inter-model operability between platforms. Until the day when we can do that (which is a long way off, but much closer with Rhino3D/GH…"
Michael Roberts replied to Jon Mirtschin's discussion Models created with assistance of Geometry Gym in the group Geometry Gym BIM"Kudos Jon:
Your dedication and talent for providing innovative solutions in the area of structural engineering are appreciated and impressive.
Are you aware of a recent article in a prominent Structural engineering magazine that claims there is no…"

Michael Roberts replied to Michael Roberts's discussion Array of breps along a curve"There are special elements that need to be referenced or those that know will discount it, however, as you can see, the effect of your links beyond the initial starting ones make the image very workable! Gotta love the power of RHino3D/GH/Flamingo…"
Florian Frank replied to Michael Roberts's discussion Array of breps along a curve"mh ya it should be possible, but obviously a lot more work. you have to get sure that it always fits with the next piece...which needs stretching on this brep in the middle part, so that the actual diameter of the chain element is not affected by…"
Michael Roberts replied to Michael Roberts's discussion Array of breps along a curve"Thx Florian:
Very nice. This would certainly perform the intent. It looks as though you are building the chain from start, which is also cool.
Do you think that it's possible just to do the same with a referenced brep only? Therefore, the chain…"
djordje replied to Michael Roberts's discussion Splitting up quads to triangles, using the points for Hydro, Wind?"Hi Michael,
Just use "Mesh Explode" component (one grouped in purple) before "Weaverbird's Vertices component".
In my example I used surface, as in input. It does not matter, you can use your mesh instead.
So basically…"
Florian Frank replied to Michael Roberts's discussion Array of breps along a curve"Hi Michael,
you can divide the curve and cunstruct planes on those divisionpoints aligned each to the next point of this division. So further you can rotate each others plane normal 90 degrees et voila you have your chain.
Hope this is what…"

Is there a way to select a Brep Geometry, then have GH use that source to place it along a curve, at the GH-based division points, remaining true to the planarity of the line (i.e. orientating it's insertion or centroid point properly on the curve)?Sort of an array, but something like the sphere 3D which can be placed on nodes, points, or division points, etc.Thinking for use in a chain link on a parametric line, to avoid drawing each time it changes.ThxSee More

Michael Roberts posted a discussionReal Time Catenary Cable Behaviour with Rhino 3D+GH+Kangaroo Simulation Demo
http://www.youtube.com/watch?feature=player_detailpage&v=aCgDmpXccxERecently had a chance (and time!) to check the output of a real-time cable analysis with structural design analysis software.Results are uncanny for those the software can check, however, most structural programs fall short where GH/K take it to the next level and get parametric in real-time ;)Click on the HD setting next to vid settings…See More
Michael Roberts replied to Rupert Todd's discussion Units (mass & force) in the group Kangaroo"For those using non-metric, Alternate units seem to work as ft for length, force, kips, Area (ft^2). Or, use # instead of kips: Depend on E, G, etc. ;)
As long as you are consistant with the units throughout, it should all add up.
Also, increase of…"
