COMSOL 6.4 - Job Configurations

Job Configurations

The node (

) automatically appears if the Job (Subnode)node has content. Or to make it available in the context menu, click the button (

) and select in the dialog.

The following categories of job configurations each correspond to a node:

•

Parametric Sweep, Function Sweep, and Material Sweep

•

•

Cluster Computing

•

•

Design of Experiments and Uncertainty Quantification

•

Most of these job configuration nodes share the common set of subnodes listed in Table 20-11. In addition, a Batch job configuration node has a default Batch Data (Subnode) subnode that in turn stores External Process (Subnode) nodes, which contain information about batch jobs. Cluster Computing job configuration nodes do not have any subnodes and must point to a Batch job configuration. Optimization job configuration nodes do not have any subnodes but include parametric jobs.

Advanced Study Extension Steps

Table 20-11: Parametric and Batch Subnodes.
Icon	Name	Description
	Derived Value (Subnode)	Runs a Derived Values node.
	Evaluate Derived Values (Subnode)	Evaluate some or all Derived Values nodes.
	Export to File (Subnode)	Runs an Export node and saves it to a file.
	External Class (Subnode)	Runs the main method of an external compiled Java® class.
	External Process (Subnode)	A Batch subnode that contains information about the batch processes that have been started by the Design of Experiments (Job Configurations) node. Each External Process node is associated with a started batch job.
	Geometry (Subnode)	Runs a geometry sequence.
	Job (Subnode)	Runs a Parametric, Batch, or Cluster Computing job node.
	Mesh (Subnode)	Runs a meshing sequence.
	Plot Group (Subnode)	Runs a Plot Group node.
	Save Model to File (Subnode)	Stores a model in the state that it is at that point in the job configuration.
	Solution (Subnode)	Runs a solver configuration.

Table 20-12: Job Configurations Node - Context Menu Options.
Icon	Name	Description
	Show Default Solver	Shows the default job configuration node (if any) that corresponds to the study step nodes in the study.
	Parametric Sweep (Job Configurations)	Adds a Parametric Sweep node, which can loop over a given set of parameters. For each set of parameters, it runs the sequence defined by its subnodes. You can combine the sequence with other Batch, Parametric, or Cluster Computing sequences in a hierarchical way by adding a job configuration that points to another node.
	Design of Experiments (Job Configurations)	Add a Design of Experiments node to evaluate quantities of interests. The evaluation is done by running the sequence defined by its subnodes for each set of parameter values. These parameter values are generated using various sampling methods. The outputs include the computed quantities of interests and their corresponding surrogate models.
	Uncertainty Quantification (Job Configurations)	Adds an Uncertainty Quantification node, which automatically includes a Design of Experiments subnode. The Design of Experiments executes the entire sequence defined by its subnodes, generating data that the Uncertainty Quantification node uses to perform statistical analysis.
	Function Sweep (Job Configurations)	This is a special version of a parametric sweep that sweeps over functions defined under a Switch node that you add from Definitions > Functions.
	Material Sweep (Job Configurations)	This is a special version of a parametric sweep that sweeps over materials defined under a Switch node that you add under Materials.
	Batch (Job Configurations)	Adds a Batch node to run batch jobs. The Batch job has a special Batch Data (Subnode) subnode that collects External Process (Subnode) subnodes containing job status information.
	Cluster Computing (Job Configurations)	Adds a Cluster Computing node, which is useful when you want to submit a batch job to a job scheduler to run the model in distributed mode as a batch job.
	Optimization (Job Configurations)	This node can be added together with an Optimization study that is using a gradient-free optimization solver. It shows which parametric sweeps run during the optimization.
	Sequence (Job Configurations)	Runs job sequence steps just like the Parametric feature, but it only runs them once without any parameters or sweep. It is similar to the Batch feature, but does not create a batch job, it just runs the steps. You can use it to store models and results to file, for example.
	Delete Configurations	Deletes all jobs under the Job Configurations node.
* Optimization is an option with the addition of the Optimization Module. ** Uncertainty Quantification is an option with the addition of the Uncertainty Quantification Module.
