Hi,
Prepomax 1.5.6 has some problem with Point Springs.
I’m using as reference my validation file for the Compression Only/Surface Spring Suport (simple balance).
I have substitute the Surface Spring/Compression Only Support by it’s equivalent springs and it’s not working no matter what I try.
U3 Displacement with just the Right Springs should be 7.5 mm
U3 Displacement with Right and left Springs should be 6.66 mm
It is not a ccx bug
I would say you are dividing the Spring Stiffnes by the contributive area. That’s not the case here.
It is a Point Spring defined by the user.
It is a bug. I have fixed it. I will create a new release shortly. Please give it a try.
The problem was that the spring stiffness was correctly entered into the .inp file but the springs were connected to non-existing node id 0.
Sure!!.
NOTE: I own you a response about adding the dummy contact. This has emerge preparing my response.
I will consider this bug as fixed.
