Mastodon Outputs Action

Create required objects for requested output.

Description

The Mastodon Outputs action creates the required objects for creating MASTODON simulation outputs. Currently this action provides the option to create the stress and strain AuxVariables and AuxKernels automatically if the user needs stress and strain outputs from the simulation. The Mastodon Outputs action is created by the Outputs sub block of the Mastodon block as shown in the example input file below.

note

The Mastodon Outputs action is under development and more functionality will be added in the future.

Constructed MooseObjects

Table 1 below lists all the objects created by the input parameters in the Mastodon/Outputs block.
