Spatial Evaluation Method—Basic and Dynamic Analyses
In defining a spatial evaluation method, you specify the type of value you want
Creo Simulate to calculate for the measure, and indicate whether you want
a global or a local measure. For most quantities you select,
Creo Simulate provides two option menus for spatial evaluation. The first menu enables you to select a spatial evaluation method. The second determines whether the software considers the entire model or selected areas of the model, or samples various points within a specified radius.
You can select from the following spatial evaluation methods, depending on which measure component you choose:
• At Point—Creo Simulate treats the measure as a local measure, calculating the value at a datum point or points you select. If you click the Advanced button and select an option from the second menu, Creo Simulate calculates the value over a selected group of entities touching the point.
• Maximum—Depending on your selection in the second menu, Creo Simulate can treat the measure as a global or as a local measure, searching the entire model or its selected area for the quantity's maximum value. This value is the most positive value, regardless of the magnitude of the value. For example, if the model stress ranged from –10 to –25 ksi, the maximum would be –10 ksi.
This option is inactive if you select Min Principal or Max Abs Principal for a Stress or Strain quantity.
• Minimum—Depending on your selection in the second menu, Creo Simulate can treat the measure as a global or local measure, searching the entire model or its selected area for the quantity's minimum value. This value is the least positive value, regardless of the magnitude of the value.
This option is inactive if you select Max Principal or Max Abs Principal for a Stress or Strain quantity.
• Maximum Abs—Depending on your selection in the second menu, Creo Simulate can treat the measure as a global or local measure, searching the entire model or its selected area for the quantity's maximum absolute value. This value is the largest value, regardless of the sign of the value. For example, if the model stress ranged from –10 to –25 ksi, the value would be –25 ksi.
This option is inactive if you select Max Principal or Min Principal as the component for a Stress or Strain quantity. This option is also inactive if you select Magnitude as the component for one of the other quantities.
