- Introduction to MotionSolve

- Model Simulations
  - Simulation Types
    Based on your input, MotionSolve formulates the equations of motion characterizing your system. Simulation refers to the process of solving these equations using a computer.
  - Transient Simulation
    Transient simulation can be performed on systems with zero or greater degrees of freedom. For systems with zero degrees of freedom, kinematic simulation is used. For systems with more than zero degrees of freedom, the dynamic simulation is used.
  - Static Simulation
    Static simulation is useful for finding the equilibrium configurations for models having one or more degrees of freedom. The equilibrium is defined as that configuration where all forces and moments acting on all parts in the model at rest equal zero. MotionSolve provides two different algorithms for static simulation.
  - Quasi-Static Simulation
    Physically, quasi-static means that the system is being driven extremely slowly so as not to engage any transient dynamics. Mathematically, quasi-static simulation is a sequence of static simulations performed over a given duration. It is useful when your model contains time-dependent forces or motions and you are interested in the sequence of equilibrium configurations your model passes through.
  - Linear Simulation
    General multibody systems are almost always nonlinear. Nonlinearities may arise from force elements with nonlinear constitutive relations, constraints, or kinematics. In general, nonlinear systems are notoriously difficult to analyze. You may find it useful to study linearized versions of your models created using MotionSolve.
  - Perform Sequential Simulations
    These four basic simulation types - transient, static, quasi-static, and linear - can be combined in general ways to exercise your models in complex ways.
