Hello world :)I did a fast search for information on the element type that Karamba uses, but it was not successful. Is there any place where I can get information on the type of element and its…Continue

### Creating a mathematical curve10 Replies

Hey world,- I was wondering, what is the simplest way of defining a curve based on a mathematical formula? Both F(t)=x(t, a1, a2...)+y(t, b1, b2...)+ z(t, c1, c2...) and F(x, a, b ,c...), and/or any…Continue

"Thank you, great and precise info, it will be of much help! :) I assume then that by increasing the degree of the interpolation, you amongst other things increase the number of controlpoints defining the curve; allowing it to "wiggle"…"

"Every freeform curve in Rhino is a nurbs curve. There is no other kind of curve that can handle freeform shapes in Rhino. Well, that's not true, we also have Beziers and Polynomials, but they are purely SDK curves, they are never inserted into…"

"Thank you. But isn't an Interpolated curve by definition not a NURBS curve? Grasshopper Primer p 69 implies that it is not a NURBS curve (except for w. degree 1, which makes sense :)).  "

### The interpolation curve used by Grasshopper

Hello world, a quick question about the interpolation curve.I have tried finding this information in the GH Primer as well as in previous discussions, but no luck. What type of curve is the interpolation curve used by grasshopper? I want to be able to predict the consequence of changing its curve degree. I have found some articles describing B-splines and the differences between the degrees, but I need to confirm/disconfirm that this is the curve used :) If you know of any source of information…See More

" model view, as the name says, just views a model (analyzed or not). to affect the analysis, you have to change parameters before the actual 'analyze model' component."

Robert Vier replied to Daniel Eika's discussion The Mesh Load component in the group karamba
"Hello! For others to be helpful, nice practice is to have a picture describing the problem somehow (.. and also for us). So, the mesh load component takes the load vector [kN/m2] on each face and distributes the resultant load [kN according to…"

"It's hidden in the render settings. I'm not sure whether this will actually affect the calculation. You get some slightly differnent coloration depending on the number of faces and the subdivisions, but this might be only a display issue."

Daniel Eika added a discussion to the group karamba

Hello world, I thought I could shear I difficulty I am having with you.I have managed to create a set of beams that I am satisfied with ( a rotational symmetric shell ). However, I have alot of difficulty with the interpetation of the load. It is crucial for me to be able to use the "local to mesh/global/global proj." feature of MLoad. I am not able to discretize the area between the beams to the mesh faces and corresponding positions for point loads. Do you have any advice here?I tried drawing…See More
