aybe cause this problems.
.
maybe we can rotate this vectors in a slight angle to produce smooth principal curvature lines.so i set a point to test my thought. and i put following codes into yours,but it did work to specific curve. it cannot apply to several curves.
can you give me some advice?
.
thanks a lot!

If (Not IsNothing(PrevDir)) Then
If (dir.IsParallelTo(PrevDir, 0.5 * Math.PI) < 0) Then
dir.Reverse()
End If
if (dir.IsPerpendicularTo(PrevDir,rAngle) then
dir.rotate( fAngle ,crv.Normal)
End If
End If

this:
Private Sub RunScript(ByVal pt1 As List(Of Point3d), ByVal pt2 As List(Of Point3d), ByRef A As Object)
Dim myLine As New Line
Dim arrLines As New List (Of Line)
For i As Integer = 0 To pt1.Count - 1
myLine = New Line (pt1(i), pt2(i))
arrLines.Add(myLine)
Next
A = arrLines
End Sub
I then get this error:
Error: Overload resolution failed because no accessible 'New' is most specific for these arguments: (line 90)
If I rewrite (and change the access to Items NOT List) to:
Private Sub RunScript(ByVal pt1 As Point3d, ByVal pt2 As Point3d, ByRef A As Object)
Dim myLine As New Line
myLine = New Line (pt1, pt2)
A = myLine
End Sub
..then it works pefectly!Is there a bug with accessing list items? Or have I been staring at the screen for too long and I'm missing something very obvious?!Thanks,Toby…
nal vector.(see pic 1)
Second: Holding an abstract mesh or surface with a 3D grid structure. Basically creating 90 degree vectors on an uneven surface coming out of the object, sort of like a cactus with a grid pattern. (see Pic 2)
Third: I think #1 answers this issue: when the lines hitting the rough surface go in two different grid directions, their intersecting points are too close together. Structurally these points can be united and the vectors would be reduced. Manually deleting these lines after being baked is currently the only option. It would be so cool if there was a mathematical arrangement that would connect points that are within a certain distance to one another. (see pic 3)
…
. since there are going to be multiple units facing different directions, each unit will be calculated differently based of their respective plane.
The following screenshots can explain the situation a little better
So Lets say the vector is pointing from the operating unit to the position of the sun, an the plane underneath is where I would like to measure the angle from
this second picture shows how each unit should function, so the measured angle doesn't exceed 90 degrees. what I did is zeroed the z value for the sun position to get a project vector. The problem with this solution is that it only works for XY planes, where I need to have a lot of planes that are specific for each unit and its orientation.
Help would be much appreciated…
problem is that the values of the isocurves are plotted not always in the same way: sometime parallel to the curves, sometime perpendicular.
In the following case, for example, i would like to turn the values of 90°(to get them parallel to the curves).
in order to have something like this:
How can i do that (without baking them)??
Thanks in advance

till quite rough.
I went through your attached log but it seems to be a successful run, perhaps the error log wasn't attached. In any case, I believe we have identified this issue. The goal of the update fvSchemes component was to apply schemes to finalized meshes in an automatic way. While this is useful for new users it is also a dangerous thing to do in CFD studies.
The component works by relating mesh quality to the mesh non-orthogonality, which the checkMesh component reports. While non-orthogonality is one of the important criteria of mesh quality it does present difficulties on some kind of meshes, especially like the simple cases that BF has been meshing so far.
The example case of simple box buildings in a wind tunnel above for instance will appear as a good quality case for even the lowest of cell-count meshes, simply because it is an orthogonal geometry. That means that checkMesh will probably report low values (imagine an empty blockMesh of 10m blocks has a non-orthogonality of 0) which in turn means that higher order schemes might be paired with actually low quality meshes. This I believe is causing problems.
I posted a possible solution to this here https://github.com/mostaphaRoudsari/Butterfly/issues/57. The idea is that Buttefly provides additional options to the users, enabling them to choose between first-order (faster, more robust, but lower quality schemes) and second-order (slower, less robust, but more accurate) schemes depending on mesh quality, stage of assessment, etc. In cases like the above mesh quality a first-order scheme might provide a better option. To test this I am attaching an fvSchemes file you can use by replacing yours in the /system folder of the case.
As a note however, I would like to stress there is so much that a tool like Butterfly can provide in this area. Meshing is a quite complicated and demanding part of the process, involving a lot of trial and error. Sometimes the problem is just the mesh and not the solution options (GIGO stands true in CFD as well). It does however get easier with experience. The safe advice is the simplest one: when changing solution options doesn't help, refine mesh and run again.
Kind regards,

ly fabricated interventions and interactive electronic performance art installations in Barra Funda. Along with other experts, these tutors will teach how to use and apply new design technologies, notably Rhino and Grasshopper (and numerous plug-ins including GECO, Galapagos, Kangaroo and RhinoCam); Arduino and Processing; and the use of laser-cutters, rapid- prototype machines and CNC routers and mills.
Alan Dempsey of NEX, was in 2010, selected by the Centre for European Architecture/Chicago Athenaeum as one of the 40 most significant architects in the EU under 40. In 2008 he was selected by the British Council as one of the six most significant Design Entrepreneurs. He previously worked with Future Systems, OCEAN and Homa Farjadi. Alan was an AA Unit Tutor and is Director of the AA Independent’s Group (www.independentsgroup.net), which facilitates research into the use of computational design and fabrication. Alan has lectured, exhibited and been published worldwide. His work has received a number of awards, including a LEAF award for Spencer Dock Bridge, and a D&AD pencil for the [C]space DRL 10 Pavilion.
Robert Stuart Smith of Kokkugiais a Studio Course Master at the AA DRL. Robert previously worked for Lab Architecture Studio and Nicholas Grimshaw & Partners. He focuses on self-organisational systems and developmental growth, pursuing polyvalent and environmentally responsive affect. He leads consultation to Cecil Balmond on non-linear algorithmic design research. Kokkugia has projects in the USA, UK and Mexico, and is exhibited and published internationally.
Iván Ivanoff is an artist, programmer, and researcher. He searches for new forms of communication for the society of the future and is the director of different Media Labs worldwide. He founded the artistic collaborative i2off.org+r3nder.net, which develops multi-media and interactive projects, and Estado Lateral Media Lab to investigate and develop new technologies.
The Barra Funda district of São Paulo was once characterised by a mix of small industrial, commercial and residential programmes, but, as economic policies have favoured larger production industries, numerous companies have abandoned the area. In response, the workshop proposes the creation of new types of smaller industries to produce a mix of both consumption and production, manifested through micro-manufacturing interventions that can co-exist alongside retail and housing. Computational design and digital fabrication could be used to help create these new micro-industries, which in turn will help empower local craftsman to produce and sell directly to consumers through micro-manufacturing, located in small urban workshops.
The workshop will tap into emergent gallery scene of Barra Funda and local initiatives that use computational technology to introduce a new cultural and economic impetus. The workshop is a part of the International Festival of Electronic Language (FILE), an exhibition of interactive electronic technology, and will import these electronic technologies out of the galler, collaborating with local manufacturers, artists, and activists, with a goal of disseminating a high-tech yet low-cost and small-scale fabrication systems to promote this new micro-industrial movement. The workshop is open to architecture and design students and professionals worldwide.…
