The model has the same number of unknowns and equations: 1805
The model could not be deduced to be symbolically well-posed.
The model has
1777+4*(size(world.x_label.lines, 1)+size(world.y_label.lines, 1)+size( world.z_label.lines, 1))
scalar unknowns and
1743+(if spring1.lineForce.fixedRotationAtFrame_a then 12 else 3)+(if spring1.lineForce.fixedRotationAtFrame_b then 12 else 3)+(if not Connections.isRoot(body.body.frame_a.R) then 13 else 22)+(if spring2.lineForce.fixedRotationAtFrame_a then 12 else 3)+(if spring2.lineForce.fixedRotationAtFrame_b then 12 else 3)+4 *size(world.x_label.lines, 1)+4*size(world.y_label.lines, 1)+4*size( world.z_label.lines, 1)
scalar equations.
However, exploiting the given numerical settings of parameters gives the same number of unknowns and equations:
