How to resent iteration counter and residual scaling values
|
For external aero simulations involving both low and high speed regions, it is often the practice to start the simulation using the segregated solver and obtain second-order convergence before switching to the coupled solver to get an added accuracy at the shocks(if any). However, switching solvers (either way) will throw off the residual scaling and the residuals after the switch can look deceivingly very good (low) or very bad (high). Though this has no bearing on the solution, this often raises question by the users. To reset the residual values and use the correct scaling corresponding to the solver chosen, do the following: - Open the residual monitor panel - Reset the Storage Iteration to 0 (default is 1000) - Click on the Plot button - Reset the Storage Iteration back to default (or any value desired) - Continue on iteration The iteration counter will be reset to 1 and proper residual scaling will be applied from hereon forward. The solution is not modified in any case. |
