Review Data Transfer and Participant Diagnostics in the Transcript

Review the Transcript output for the following coupling steps and iterations.

Coupling Step 1, Iteration 1

All participants update in the first coupling step, regardless of their Update Control settings. In this step, both participants are executing and solving to ensure that Maxwell begins by receiving a representative temperature and generating a representative loss.

Data Transfer Diagnostics

Temperature:
Maxwell received temperature. Temperature transfer convergence diagnostics are presented for the source and target sides of the interface for this and every other iteration.
- RMS Change values report progress toward specified convergence targets.
- Weighted Average values report a weighted average temperature on the source and target, respectively. These values should also be very close to one another.
- The Temperature data transfer did not converge.
Heat Rate Density:
Mechanical received losses. Heat Rate Density convergence diagnostics are presented for the source and target sides of the interface for this and every other iteration.
- RMS Change values report progress toward specified convergence targets.
- Sum values report the net heat leaving the source and entering the target, respectively. These values should also be very close to one another.
- The Heat Rate Density data transfer did not converge.

Participant Diagnostics

Because all participants update for the first coupling step, Maxwell and Mechanical both updated for this iteration.
Maxwell's direct solution completed.
Mechanical's iterative solution converged.
