The Bidirectionally Coupled Particle Tracing study ()¨is used to model the interactions of particle trajectories with stationary fields. The study creates a Time-Dependent Solver that solves for all degrees of freedom related to the particles. All other degrees of freedom are computed using a Stationary Solver. The two solvers are repeated using a For-End For loop so that a self-consistent solution is obtained, taking the bidirectional coupling between the moving particles and stationary fields into account.

See the Time Dependent study step for information about the following sections: Study Settings, Results While Solving, Physics and Variables Selection, Values of Dependent Variables, Mesh Selection, and Study Extensions.

Select an option from the Termination method list: Fixed number of iterations (the default) or Convergence of global variable. For Fixed number of iterations enter a positive integer for the Number of iterations (default 5). Any nodes between this For node and the following End For node will be repeated a number of times equal to the specified Number of iterations.

For Convergence of global variable enter the following:

This default solve sequence generated by this study step includes a loop containing the For and End For nodes. The options in this section correspond to the General section of the settings window for the For node.
