Initial Conditions Section

Initial conditions allow you to set the values of certain state variables at the start of a simulation.

These variables help to define the base state of the model and might compensate for modeling omissions or inaccuracies.

Unlike restraints, which fix certain values during a simulation, the initial conditions are free to evolve from their base state during the course of the simulation.
Temperature
Defines the temperature in a region for a thermal analysis case.
See Applying Prescribed Temperatures.
Initial Stress
Defines the initial stress of a body.
See Applying Initial Stresses.


Initial Velocity
Defines the initial velocity of a body or fluid.
See Applying Initial Velocities.


Initial DOF Rotational Velocity
Defines a rotational velocity about each node in a region.
See Applying Initial DOF Rotational Velocities.


Void Ratio
Defines the ratio of volume of voids to volume of solid material.
See Applying Void Ratios.
