An initial conditions simulation ensures the proper assembly of your
Model before other
Simulations. It checks to ensure that all constraints and initial conditions are allowable and consistent. If it finds any discrepancies, it corrects them so that there is a consistent set of values representing the state of the model and assembles the model in a more appropriate way.
For example, if initial values for displacements and velocities violate the constraint equations,
Adams Solver modifies the input displacement and velocity data to satisfy the constraint equations while minimizing the change in the input data.
