Hi,
This is because of some DoFs of your model are not properly restrained. Dx
, Dy
and Rz
Dofs second node is free to move, (because of only BeamYEulerBernoulli
behavior). So fixing those DoFs in second node fix the error:
Edited line 3 of your code and works:
var n2 = new Node(10, 0, 0) { Label = "n2", Constraints = Constraints.RotationFixed & Constraints.FixedDX & Constraints.FixedDY };
When I executed the code below, an error says: Matrix must be symmetric positive definite
Where is the matter?
