You’re going to want to investigate Dynashape from @LongNguyen. Installer Here -> DynaShape

and here is a video demonstrating this

and the graph I used

What version of Dynamo do you have?

I use dynamo 1.3

So I had a TeamViewer session with @helen60932111PLHPF yesterday and we were able to fix the issue. It was just that the ViewExtensionDefinition XML file was not set up correctly.

Dear Long,
I would like to achieve the vortex-shape shown in the image with DyndShape to determine the true minimal surface area and I am completely stuck. The surface boundaries (sections) are an ellipse and a circle. (the surface generated in the script is just an indication/sketch of what I am trying to build with DynaShape) Any idea how to start this with an ellipse/circle-based surface boundary?
many thanks in advance
Oliver

Here is my approach.

  1. Create a loft surface from the two sections (circle and ellipse)
  2. Turn the loft surface into a mesh
  3. For each edge mesh, create a Length goal with TargetLength value 0
  4. Don’t forget to create Anchor goals for the mesh vertices that lie on the ellipse and Circle as well
  5. Run the solver and the Length goals shall shrink the mesh to give you an approximation of the minimal surface

Hope you will get it working.

Bests

Long
