Environment

This is the top level of the Rigid Dynamics model.

ID table: CS_Environment

Members

System

Corresponding system.

Example:

Env=CS_Environment.FindFirstNonNull()
Sys = Env.System

Ground

Ground body.

Example:

Env = CS_Environment.FindFirstNonNull()
Ground = Env.Ground

Loads

The vector of existing loads. This includes Springs that are considered by the solver as loads, as well as force and torque joint conditions.

Example:

Xdof = 0
Friction=CS_JointDOFLoad(PlanarJoint,Xdof)
Env.Loads.Add(Friction)

BodyLoads

The vector of Body Loads.

Example:

MyBodyLoad = CS_BodyLoad()
…
Env.BodyLoads.Add(MyBodyLoad)

Relations

The vector of external constraint equations.

Example:

rel3=CS_Relation()
rel3.MotionType=CS_Relation.E_MotionType.E_Velocity

var30=CS_ConstantVariable()
var30.SetConstantValues(System.Array[float]([0.]))

var31=CS_ConstantVariable()
var31.SetConstantValues(System.Array[float]([23.]))

var32=CS_ConstantVariable()
var32.SetConstantValues(System.Array[float]([37.]))

var33=CS_ConstantVariable()
var33.SetConstantValues(System.Array[float]([-60.+37.]))

rel3.SetVariable(var30)
rel3.AddTerm(jp,0,var31)
rel3.AddTerm(js3,0,var32)
rel3.AddTerm(jps,0,var33)

Env.Relations.Add(rel3)

Drivers

The vector of Displacements, Velocity and Acceleration joint conditions.

InitialConditions

The vector of Displacements, Velocity, and Acceleration joint conditions to be used only at time=0.

PotentialEnergy

Gets the Potential Energy Measure.

KineticEnergy

Gets the Kinetic Energy Measure.

TotalEnergy

Gets the Total Energy Measure.

ActuatorEnergy

Gets the Actuator Energy Measure.

RestartTime

Specifies the starting time in a restart analysis

Member functions

FindFirstNonNull():

Returns the first environment in the global list. The table usually contains only one environment, thus it is a common way to access the current environment.

Example:

Env=CS_Environment.FindFirstNonNull()

AlterSimulationEndTime(endTime)

Overwrites the end time of the simulation.

Solve()

Solves the current analysis.

Derived classes

None
