Segregated solver comsol. This attribute makes it possible to split the solution process into substeps. If/when you come across a physics/coupling that is blowing up your convergence, try a simplifying test case where you take only the problematic one and verify that the boundary conditions and chosen solver work in isolation. Within either of these features, it can also be helpful to enable the Results While Solving option, as shown in the screenshot below, to visualize the iterations being taken during the solution. To set up the Segregated approach, right-click on the Stationary Solver or the Time-Dependent Solver feature and select Segregated to add a new Segregated feature. To set up the Segregated approach, right-click on the Stationary Solver or the Time-Dependent Solver feature and select Segregated to add a new Segregated feature. One segregated iteration consists of executing each active Segregated Step in the order shown in the model tree. Right-click on the Stationary Solver node and add either the Segregated or Fully Coupled feature. . You can move the Segregated Step nodes to change the order in which the solver runs each step. Although several Fully Coupled and Segregated attribute nodes can be attached to an operation node, only one can be active at any given time. An alternative to the segregated approach is given by the coupled solver, which is handled with the Fully Coupled attribute node. The Segregated node () is an attribute that handles parameters for a segregated solution approach. The convergence properties of a model might depend on the order of the segregated steps. wbanr gvcphn arn ktq rvko cmise cmsj spdkiao rbly ssze
