and the dissipation rate 
) the basic steps involved in the solution update are as follows:
This solver controls the solution of the Reynolds Stress transport model in all the continua for which the model is activated. The node of this solver has its own properties.
For each transported variable (components of and the dissipation rate ) the basic steps involved in the solution update are as follows:

At each iteration, governs the extent to which the old solution is supplanted by the newly computed solution. The default value is 0.6. For the theoretical background, see Eqn. 375 in Implicit Iteration . |

The properties in the Expert category are designed to be used in a temporary debug situation, at the expense of simulation accuracy and for additional memory usage. We do not recommend that you change any of these properties unless you are thoroughly familiar with the discretization techniques used in STAR-CCM+.

Prevents or allows the solver from updating the solution while iterating. |

| Ticked |
The solver will not update the solution. |
|||||||||||||||||
| Cleared |
The solver will update the solution. |

Retains or clears temporary storage at the end of the iteration. Examples include the ap coefficients, the residual, the corrections, the reconstruction gradients and the cell gradients. These quantities will become available as field functions during subsequent iterations. |

| Ticked |
Retain temporary storage. |

| Cleared |
Do not retain temporary storage. |

Sets whether or not reconstruction gradients are updated with each iteration. |
|||||||||||||||||
| Ticked |
Use reconstruction gradients from the last iteration in which they were updated. Temporary Storage Retained must be ticked. |
|||||||||||||||||
| Cleared |
Update reconstruction gradients with each iteration. |

Allows you to set reconstruction gradients to zero, so that face values used for upwinding (Eqns. (338) and (339)) and for computing cell gradients (Eqns. (372) and (373)) will be first-order estimates. |
|||||||||||||||||
| Ticked |
Set reconstruction gradients to zero at the next iteration. Gradients will remain zeroed until you clear the checkbox again. |
|||||||||||||||||
| Cleared |
Do not reset reconstruction gradients. The will be recomputed at the next iteration if they had been zeroed. |
