Components.Tests.AllComponents

Smoke test exercising all available translational components in a single model.

Replicates the structure of ModelicaTest.Translational.AllComponents.

Top chain: sliding_mass → rod(L=0) → spring(c=1) → damper(d=10) → sliding_mass1 A RelativeStates element spans from sliding_mass.flange_b to damper.flange_a, measuring the relative displacement and velocity across the rod and spring.

Branch from sliding_mass.flange_b: A Force source (driven by a sine signal) and a SpringDamper(c=1, d=1) connect to sliding_mass2. A Fixed ground provides the reaction reference for the two-flange Force component.

ElastoGap branch from sliding_mass2.flange_b: An ElastoGap(c=1, d=1) connects to sliding_mass3. A FixedTemperature closes the thermal energy balance.

Position branch: sine → position (Filtered) → sliding_mass4 Speed branch: sine1 → position1 (Speed, Filtered) → sliding_mass5 Accelerate branch: sine2 → position2 (Accelerate) → sliding_mass6

Initial conditions: all masses at rest at the origin, all relative displacements and velocities zero.
