Linear springs
Linear springs in Ashes are applied on nodes and modeled as a support (see Keywords) with a stiffness (in N/m for translational springs and N/rad for rotational springs). When a spring is applied onto a node, the node will experience a load
$$L_i=K\cdot d_i$$
where
- $$L_i$$is the load (either a force or a moment) in the direction corresponding to the degree of freedom$$i$$
- $$K$$is the spring stiffness
- $$d_i$$is the displacement of the node corresponding to the degree of freedom$$i$$
