"I was assuming so. Actually, I wouldn't mind so much how they were spaced, as long as the density is proportional to the number of elements specified for the calculation. That way one may simply interpolate the results afterwards,…"

I'm working on a hollow solid, i.e solid cut out of a bigger solid with gravity as force.Now it would be useful to preserve the volume of the inner solid. Could this be added as a restraint easily?A…Continue

"Kristoffer,
We don't have a traditional finite element mesh with nodes to parameterize the interior of the solid. How would you like to specify the sample points inside the solid? On a regular grid? From an external…"

Solid export with data on nodes
Hi,we are doing some analysis of solids which we are not able to work with using traditional software (GSA).What we are interested in is getting the volumetric data out of the solid, in particular we want the stress tensor together with the coordinates for the points inside the volume.Right now it is possible to bake the mesh together with the colours. This way it is possible to reverse engineer the values on the surface (and slices) of the solid and interpolate the values inbetween.This it is…See More

Solid mesh support
As a temporary solution to the issues in http://www.scan-and-solve.com/forum/topics/scan-solve-for-surface-andI think it would be sensible to support solid meshes in SnS.As the offset operation usually works a lot better for meshes than for surfaces, a common approach to creating a solid from a surface is first to mesh it, then offset it and tick the 'solid' option.However, at the moment this solid is not…See More

"Ah, I knew I was not imagining this properly. Yes, that is a "difficult constraint" -one that suggests large deformations and iterative form-finding.
We'll put it on the wish list, but I think this may become an end-user…"

"Yes this is the topology I imagine. However, I would like to allow the shape of the inner sphere to change, with only the volume being preserved. In the above example under gravity, I would guess maybe a kind of sessile drop would be the resulting…"

"I'm pretty sure I'm not properly imagining what you are describing. I'm envisioning a hollowed out sphere with some boundary thickness. Of course, in Rhino, the inner surface must be connected to the outer surface to make…"

Volumetric restraints
I'm working on a hollow solid, i.e solid cut out of a bigger solid with gravity as force.Now it would be useful to preserve the volume of the inner solid. Could this be added as a restraint easily?A crude approximation is to add a pressure force to each of the facets of the inner solid, but there is no guarantee that this preserves the volume in all cases. Any thoughts, or plans on adding it to SnS? Thanks,KristofferSee More

"Today, I came to a situation where i would like to add rotational constraints to a face, ie fix some directions of rotation only. Is this a quick, possible future addition?"

"Thanks for your reply Vadim.
I'm happy to hear it is on the TODO list.
The scenario I'm in, and which I assume is a common one, is to model for example a thin shell, hence the offset must be smaller than the radius of curvature anyway,…"
Kristoffer Josefsson replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"Yes, but unfortunately this doesn't work for all kinds of surfaces or meshes... but the distance field approach could probably be implemented inside SnS."
Kristoffer Josefsson replied to Germano Pecoraro's discussion 'Scan & Solve for surface and poly-surface.'
"I second this. A thin shell model should be able to work with a surface and a given thickness, since SnS works with just querying points inside a volume, the volume can be defined by a distancefield around the surface."
