No headersThe Convergence tab of the RTM/SRIM solver parameters (Midplane/Dual Domain) dialog is used to specify values for solver convergence related analysis inputs for an RTM/SRIM analysis.
| Convergence tolerances apply to the % change in a function value from one iteration to the next, and are used to identify when a solution has converged. As soon as this % change value falls below the convergence tolerance, the solution has converged. |
| Specifies the maximum number of iterations that the program will perform in order to solve the flow rate equations. The program will continue until either the maximum number of iterations have been surpassed, or the error limit is less than the specified value. |

| Specifies the maximum number of iterations that the program will perform in order to solve the melt temperature equations. The program will continue until either the maximum number of iterations have been surpassed, or the error limit is less than the specified value. |
| The nodal growth scheme controls the size of each flow front advancement step taken in a Dual Domain Flow analysis. The option (default) allows multiple bands of elements to be filled in a single time step. The option allows only a single band of elements to fill each time step. Select Single if you wish to increase the accuracy of the fill pattern prediction but note that the computation time will be increased. |
| For certain materials with high temperature or shear sensitivity, extrapolation of viscosity values to high shear rates may introduce instability in the flow calculations. This option relates to a corrective algorithm that eliminates the instability at high shear rates. |
