SPH::solid_dynamics::SpringOnSurfaceParticles Class Reference

Exerts spring force force on the surface in the form of acceleration to each particle. The input stiffness should be defined in Pa/m. The stiffness is scaled by the surface area of the particle to get N/m The force is applied to all the surface particles. The spring force is calculated based on the difference from the particle's initial position. Only for 3D applications BodyPartByParticle define the ody part that the spring is applied to. Only for uniform surface particle size. More...

Detailed Description

Exerts spring force force on the surface in the form of acceleration to each particle. The input stiffness should be defined in Pa/m. The stiffness is scaled by the surface area of the particle to get N/m The force is applied to all the surface particles. The spring force is calculated based on the difference from the particle's initial position. Only for 3D applications BodyPartByParticle define the ody part that the spring is applied to. Only for uniform surface particle size.
