Hey, i’m moddeling a hypar (with different parameters) and would like to find the forces on the edges (different structure) caused by the wind function. So far so good. I generared extra points besides the hypar. Springs with given stifness are between the extra points and the hypar mesh. I calculated the displacement of the hypar mesh boundarys. Force on the structure = Stiffness spring x displacement. There are some problems.
1: the result mesh is very edgy and the mesh/sail is not a smooth one.
2: the calculation of the force (in excel) is not consisent. When I take stifness = 100 or stiffnes = 1000, the displacements don’t follow up (factor 10), so I get other force results. (Is something wrong with the springs? Does the kangaroo engine do something I don’t understand?)
3: Are there other possible ways to find the forces acting on the other structure (where the hypar is attached to)?
I really hope you can help me, because I have been struggeling in my thesis for days.
