True, I need to take a closer look at the previous solutions and properly understand them.
I did animate some of the points earlier, and for the most part it worked well, but when two points are close and they move past each other, the flip is quite extreme.

That look's so good eetu! I'm having license issues at the moment, but will try it as soon as posisble.

…and when you've had a go in Houdini, post the hip file here 
I'd like to try too (once I actually get Houdini working).

OS?
Anit-Virus software getting in the way?
Windows 8.1 Pro, standard windows defender anti-virus. Just tried disabling the anti-virus and the firewall, then running as admin. Still have the same issue.

Hi all,
The issues I'm having with getting Houdini started just keep getting worse and worse. Initially everything worked ok and it automatically installed non-commercial licenses. But then it stopped automatically installing so I had to use the Houdini License Administrator along with this page:
http://license.sidefx.com/get_nc_license.php [license.sidefx.com]
in order to install the license.
Now I'm being told that the “License server is not running” by Houdini License Administrator.
I've checked the services and HouiniServer and HoudiniLicenseServer are both running. I've also tried reinstalling and disabling the firewall completely, but nothing has worked and I cannot start Houdini at all.

I'll look into that chevita…though, if you can give any more information about the method that would be great. Houdini is intimidating at times

That worked a lot better than what I had previously.
Do you have any ideas about how to get the spheres to grow while being simulated with finite elements? (or cloth if that's easier, just something that makes them look organic and squishy)

…is there a way to get metaballs to refuse to connect at a certain point in time?
The main thing I'm having difficultly with is essentially simulating an object who's number of points is changing (due to metaball remeshing, or just general changing of the mesh). If anyone has any resources on simulating geometry while it's changing that would be a great help.

That looks more like it. I'll download and take a look as soon as possible 
Thanks again!

Ahh, thanks again eetu
It's a shame that the effect isn't quite what I was after
I was going to turn the spheres into FEM spheres and make them grow (somehow) so they squash up against each other. Using this force field doesn't seem to work well enough for keeping the spheres attached to the surface.
If you have any suggestions I'd love to hear them
I've attached my current scene - imagine those spheres squshing up against each other and you'll see what I'm after.

Ok, I seem to be stuck. I have my field force set up in my DOP network, but the simulation just seems to be inactive or something, because my array of sphere objects just do not react to the field force at all.
Any ideas?

Ah yes - thank you pezetko! Now to get this field to act as the force in a simulation. I'm going to assume that I can just export from the vopsop to a parameter named ‘force’and that should work?

I'm trying to follow the example in the docs for the Volume Gradient vopsop, but having no success. The docs say this:
I tried this and it shows nothing in the viewport at all. See attached file.
It seems so simple I'm not sure what I could be doing wrong here
“For example, create a sphere and a point (with the help of the Add SOP). Connect the sphere to the IsoOffset SOP and change it to SDF. Next, connect the point and IsoOffset to the VOP SOP. In the VOP SOP, connect P in Globals to the N output using the Volume Gradient. In the viewport, the point normals will show you the direction. For it to work, the point must be located within the limits of the SDF field. Because the output yields the normalized data, it shows only the direction.”

Hi all,
I'm trying to attach many FEM (or RBD initally for testing purposes) to an arbitrary surface, but I'm not sure how to go about this, but I have a general idea to try and create a vector field that points towards a surface.
Take a look at the attached image and imagine some field lines following those normals.

So it's definitely a limit with the ramp parameter that it cannot be > 1?
From a user point of view this is a bit weird. When setting up a ramp that corresponds to a distance it would be really useful if the ramp parameter is the actual distance, not some normalized version of distance
Whats weird is using a ramp, when you can use a point cloud to easily to that.
Rob
Could you elaborate?

I don't think metaballs would work. I essentially need one object to split apart and become two, all the while being effected by a FEM simulation so they can all squash together.
