The Solver Configurations node (
) contains all solver configurations defined for a study (see
Figure 20-1). It displays if it has content, or — to make the node available in the context menu — click the
Show More Options button (
) and select
Solver and Job Configurations in the
Show More Options dialog box.
A model is solved by computing a solver configuration — a scheme for computing a solution. A solver configuration is represented by a
Solution node (
) which stores both a sequence of subnodes, specifying how to compute the solution, and the solution itself — once it has been computed. Typically, such a solver configuration contains information about which configuration to use for physics interfaces, geometry, and mesh, which variables to solve for, and which solvers to use for the type of study to perform. You can also solve a model by directly computing a study; doing so first sets up a default solver configuration and, in some cases, one or more
Job Configurations.
To display the solver that corresponds to the study steps in a study and the current physics interface settings, right-click the main Study node (
) (or the
Solver Configurations or
Job Configurations nodes) and select
Show Default Solver (
). See
Solver Suggestions for information about physics-specific solver suggestions in the default solver.
To reset a solver configuration to the default sequence for the current study steps and settings in the parent study, right-click the solver configuration node and select Reset Solver to Default (
). The solver sequence under the solver configuration node is then reset to the default solver settings that you get when you select
Show Default Solver and that the study uses if you have not made any changes to the solver settings. Using
Reset Solver to Default can be useful if you have tried various solver settings and want to return to the default solvers without having to create a new solver configuration.
You can also right-click individual study step nodes and choose Reset Solver to Default for Selected Step to only reset the solver settings in the currently enabled solver configuration to the default for that study step.
From the main menu, click the Show More Options button (
) and select
Study and Job Configurations in the
Show More Options dialog box. Then right-click the
Solver Configurations node and choose
Create Custom Solver (
). This adds a
Solution node without any added solver settings or other nodes. Use this option if you want to create a fully user-defined custom solver scheme.
To create a copy of the solution dataset, right-click the main Study node (
) or the
Solver Configurations node
(
) and select
Create Solution Copy (
). A copy of the solution then appears as a
Solution - Copy node (
) under Solver Configurations and a corresponding
Solution - Copy dataset (
) under
Datasets in the
Results branch. This can be useful if you want to rerun the simulation with some changes to the model or solver settings. The first solution is then available in the
Solution - Copy dataset so that you can postprocess and analyze multiple solutions. You can also right-click a
Solution node (
) under
Solver Configurations and choose
Solution>Copy (
) to create a copy of the solution dataset for that solution.
Select Delete Configurations (
) to delete all solvers under the
Solver Configurations node.
Under Solver Configurations, right-click a
Solution node and choose
Solution>Store on a Single Node to specify that the solution should only be stored on a single cluster node. Choose
Solution>Store on All Nodes if the solution should be stored on all cluster nodes. Choose
Solution>Store Solution Using Distributed Storage if the solution should be stored using a distributed storage on clusters, which can improve performance using parallel I/O.
