The Field data models menu option generates new field samples from selected amplitudes.
The respective random field model must exist in the database.
You must select the complete set of amplitudes, starting at
[1]. For example, select:amp[pstrain][element]_shape[1]amp[pstrain][element]_shape[2]amp[pstrain][element]_shape[n]
oSP3D determines the random field models that are associated with the selected amplitudes. For each random field model, the generation of field samples is carried out.
The new field quantity is named
smoothened[quantity.ident]
Usage
Simulation of random fields
Analyze a random field.
Delete computed amplitudes.
Generate new amplitudes (zero mean, unit standard deviation) outside of oSP3D. You can use CSV Files.
Import these new amplitudes.
Generate one or more new field designs.
Statistical smoothening
Eliminate noise, where noise is considered to be the variations associated with small correlation lengths.
Restore eroded data
Instead of the interpolation of adjacent values of missing items, which is the default during import, you can use Karhunen-Loeve expansion in terms of a "statistical interpolation" of the missing data items.
