The Field data models menu option validate existing random field models with imported samples.
Before executing error computation:
Ensure that a random field model has been calculated for the field quantities selected for error computation.
Ensure that validation field samples have been imported for the selected field quantities.
When you select
, error computation is performed for active field samples only. The calculated accuracy represents the random field model's ability to reproduce the samples as a relative value. When visualized, 100% means exact reproducibility. Values greater than 100% indicate overestimation of the true value.After error computations are executed, the following new quantities are added to the database:
One field quantity named
accuracy[quantity
ident
]Three scalar quantities named
err_rms[]
,err_max[]
, anderr_min[]
err_rms[]
stores the root mean square error averaged over the mesh.err_max[]
stores the largest positive local relative difference.err_min[]
stores the largest negative local relative difference
