Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino

 

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 obviously not the ideal way to go about it though.

 

According to this post:

it is something you have already looked into?

 

Cheers,

Kristoffer

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 file?

 

Do you have a particular end result in mind that might govern how the sample points are generated and the sample values are delivered or stored?

Thanks,

Michael

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, manually.

Alternatively, if you have an internal representation where you have denser sample points where there is a lot of detail, this would facilitate a more accurate interpolation. Hence, this might be a good option too.

 

In the particular application I'm looking at, I want to populate the solid with point-density depending on the magnitude of the stress field. Since I don't know the field on beforehand, it wouldn't help much if I must specify it before the simulation. Probably I would just feed in a regular grid in that case.

 

Hope that helps,

Kristoffer
