Study

A node (

) holds all the nodes that define how to solve a model (see Figure 20-1). These nodes are divided into three broad categories:

•

Solver Configurations, which contain the solvers and related configurations for dependent variables to solve for, intermediate storage of solutions, and specific solver settings. Those nodes are normally created by the study step, and you do not need to make any changes here. This branch is only initially visible if you select in the dialog box but appears after solving or if you choose from the node’s context menu.

•

Job Configurations, which contain all jobs defined for a study (distributed parametric jobs, batch jobs, and cluster computing). This branch is only visible if you select in the dialog box.

Right-click a node and choose (

), (

), or (

) (or use the Ctrl+Up, Ctrl+Down, or Delete keys) to move a node up or down, relative to other nodes, or to remove it.

Also see Study Reference to refer to another study in the model. The main node has this section:

The check box is selected by default so that plot groups with suitable default plots for the physics interfaces in the study are generated automatically when computing the solution. Clear this check box if you do not want any default plots.

The check box is selected or cleared by default based on the setting for generating convergence plots in the dialog box. Clear this check box if you do not want convergence plots to be generated during the solution process.

Select the check box (cleared by default) to make the study add nodes after all intermediate study steps in a study with multiple study steps. If this check box is not selected, nodes are only added for some study step combinations.

Select the check box (cleared by default) to create a separate window that contains a plot that shows the location of any undefined values such as Inf or NaN. Such undefined values could be the result of a division by zero, for example. For a Geometry 1, for example, the window name is .
