Specify how the random field will be built: from a data file, from simulation runs, or from a covariance matrix. THIS IS AN EXPERIMENTAL CAPABILITY.

Required (Choose One) | Build Data Source (Group 1) | rf_data_file | Specify that the random field will be built from a file of data. THIS IS AN EXPERIMENTAL CAPABILITY. | |
dace_method_pointer | Pointer to a DACE method for purposes of generating an ensemble of field responses to be used in estimating a random field model. THIS IS AN EXPERIMENTAL CAPABILITY. | |||
analytic_covariance | Use an analytic covariance function for the purposes of generating a random field model. THIS IS AN EXPERIMENTAL CAPABILITY. |
As part of the capability to generate a random field representation, the user needs to specify the data used to generate the random field representation. This data may reside in a data file, it may be generated by running a set of simulations and generating field responses, or it may be generated by a covariance matrix defined over a mesh. THIS IS AN EXPERIMENTAL CAPABILITY UNDER ACTIVE DEVELOPMENT.
Default Behavior Currently, the build_source
that is fully working is the dace_method_pointer
. The others are not fully operational.
