Cloth Pulling wires

Recommended Posts

Hi guys,

 

This is a test I have so far:

 

I'm trying to attach cloth to a wire. This was semi successful as you can see in the video. though a lot of weird things are happening. Ideally I'd like the cloth to pull the wire in the wind. It needs to be a wire with celebratory flags on it. like this:

How would one go about this? theoretically the wire should be quite low in resistance but due to the drag of the flags it should move. Am I correct in thinking that the flags should be cloth objects (driven by a wind force) constrained to a wire?

Any tips or advice are greatly appreciated :).

I took a look at the file and the first thing I thought was the hand drawn curve is kind of rough in point distribution, perhaps that is part of the problem. I followed up your drawcurve with a Refine (in unrefine mode, activate Second U, set to 1.0, set First U to 0.0) Then follow that with a resample to evenly restore points across the curve.

 

NOTE: When I did this it broke the contrsints you had setup, I think, because the point numbers changed.

 

I don't know enough about this kind of sim to help any further but I am interested in a solution.

I've just started looking at a similar problem so I had a go at your sim. 

 

I think the green constraint spheres jumping around in the sim are a good indication that it needs some sub-stepping. Also there wasn't any damping on the wire, which helps remove excess energy and jerking around.

 

I managed to get a working version by:

 

- increasing the substeps on the wiresolver

- adjusting the parameters for the wire object (physical and elastic properties)
- moving the wind force to the cloth object only (found in the drag tab).

 

 

Not a huge amount of movement on the flag but you could probably fiddle with the wind force and the properties of the cloth to get more variation.

Sorry for the late response. This's awesome :). Thank you so much. I will analyze your file and report back with findings.
