Attempting simple tensile saddle surface

I’m trying to make simple saddle tensile surface using a square mesh using only quads.

Reference image…

I get the following error in Kangaroo solver.

  1. Solution exception:Unable to cast object of type ‘Grasshopper.Kernel.Types.GH_Mesh’ to type ‘Grasshopper.Kernel.Types.GH_ObjectWrapper’.

What should be done to resolve this issue?


Stop using the word “simple” unless you can do it yourself! :sunglasses:

You had your mesh connected directly to the GoalObjects input of the Solver.
Remove this connection and the definition works.
