d having the entire surface adjust while maintaining equilateral triangles. The closest solutions I've come across are the equilateralize and shell and plate examples for Kangaroo (images below), but I don't think the definition in the equilateralize demo will work because I don't always want 6 triangles around each vertex (I want a range from 4 to 7.) The shell and plate example seems more promising, but when I open it in rhino/GH it says the C# component is old, and the code is missing. Also, the shapes I'm trying to model are much less spherical than the mesh in the demo, so I'm not sure if that method will work anyway. I'm also posting an image of some physical models that show what I'm going for.
Any advice would be much appreciated!

ow the steps of the successful run when step 1.2 is bypassed (note that the and OpenFOAM session is open in the background while running the Butterfly demo file):
1. create wind tunnel, and use different parameters of (4,4) for _globalRefLevel_ as suggested by Theodoro in this post
2. run blockMesh:
3. run snappyHexMesh:
4. run checkMesh:
5. connect the case from checkMesh to simpleFOAM and run the simulation:
6. the simulation converged at 1865 iteration, but the results visualization part has some problem:
7. so I revised this part according to suggestions from Hagit:
8. and the results can be visualized for P and U values:
The GH file used for the successful run shown above is attached here.
Now, the following is the error I got when the case from the update fvScheme component is used for simpleFOAM simulation:
the warning message on the simpleFOAM component is:

The error message from the readMe! output node is attached below as a text file.
Hope you can kindly advise what the important steps or parameters I might have missed here. I assume it might be related to OpenFOAM rather than with the Butterfly workflow...
Thank you very much!

ns about them.
It's a direction for Kangaroo I very much intend to continue developing - and I am still getting to grips with the possibilities and experimenting with how different optimization and fairing forces work in combination with one another, so I would value your input and experience.

At the moment the Laplacian smoothing is uniformly weighted, which tends to even out the edge lengths as well as smoothing the form, which is sometimes desirable, and sometimes not. It also tends to significantly shrink meshes when the edges are not fixed.
I plan to try some of the other weighting possibilities, such as Fujiwara or cotangent weighting (see [1] and [3]), as well as other fairing approaches, such as Taubin smoothing [2], Willmore flow[4], and so on. This also has applications in the simulation of bending of thin shells.
Planar quad panels are often desirable, but I'm finding that planarization forces alone are sometimes unstable, or cause undesirable crumpling, so need to be combined with some sort of fairing/smoothing, but the different types have quite different effects, and the balance is sometimes tricky.
There's also the whole issue of meshes which are circular (I posted a demo of circularization on the examples page), or conical (this one still isn't working quite right yet), and their relationship with principal curvature grids and placement of irregular vertices, all of which is rather different when the whole form is up for change, rather than having a fixed target surface [7].
I'm also trying to get to grips with ways of making surfaces of planar hexagons, which need to become concave in regions of negative Gaussian curvature (see this discussion)
and I hope to release soon a component for calculating CP meshes, as described in [8], which I think could have many exciting construction implications.
While there are a number of well developed smoothing algorithms, their main area of application so far seems to be in processing and improving 3D scan data, so using them in design in this way is somewhat new territory. There can be structural, fabrication or performance reasons for certain types of smoothness, but of course the aesthetic reasons are also often important, and I think there are some interesting discussions to be had here about the aesthetics of smoothness.
Anyway, that's enough rambling from me, hopefully something there triggers some discussion - I'm really keen to hear about how all of you envision these tools might be used and developed.

or create a form through code.
2) Add a public function to your component that displays this form, I recommend you use form.ShowDialog() for now to avoid weird conditions with non-modal forms.
3) Override the method Menu_AppendCustomComponentItems() on your Component and add an extra menu item that will show the form (i.e. when clicked, it will call the function defined in step [2].
4) Create a new class and derive it from Grasshopper.Kernel.Attributes.GH_ComponentAttributes. (if you don't want to offer double-click functionality, you can skip steps 4 to 6)
5) Override the RespondToMouseDoubleClick() method on the new attributes and also call the function defined in step [2]
6) Override the CreateAttributes() method on your Component class and construct an instance of the custom attributes defined in step [4] instead.
7) Once you've shown the form and the user has clicked OK, you need to assign values and invalidate the Component, then start a new Solution.
Here's some code:
Public Class MySpecialComponentAttributes
Inherits GH_ComponentAttributes
Public Sub New(ByVal comp As MySpecialComponent)
MyBase.New(comp)
End Sub
Public Overrides Function RespondToMouseDoubleClick( _
ByVal sender As GH_Canvas, _
ByVal e As GH_CanvasMouseEvent) As GH_ObjectResponse
DirectCast(Me.Owner, MySpecialComponent).DisplayForm()
Return Canvas.GH_ObjectResponse.Handled
End Function
End Class
Public Class MySpecialComponent
Inherits GH_Component
.....
.....
Protected Overrides Sub Menu_AppendCustomComponentItems( _
ByVal iMenu As ToolStripDropDown)
Menu_AppendGenericMenuItem(iMenu, "Set Values", AddressOf Menu_SetValues)
End Sub
Private Sub Menu_SetValues(ByVal sender As Object, ByVal e As EventArgs)
DisplayForm()
End Sub
Public Sub DisplayForm()
Dim frm As New MySpecialForm()
Grasshopper.GUI.GH_WindowsFormUtil.CenterFormOnCursor(frm, True)
If (frm.ShowDialog() = DialogResult.OK) Then
'Harvest values from form and assign them to local variables
Me.ExpireSolution(True)
End If
End Sub
