Spatial Evaluation Method—Thermal 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. If you select Temperature, Temperature Gradient, or Heat Flux quantities, Creo Simulate provides you with 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.
If you use this spatial evaluation method for heat flux or temperature gradient, you may want to define a measure for more than one point so that you can get a better idea of overall heat transfer and temperature change.
• Maximum—Searches the entire model or the specified area of the model 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 temperature ranged from –10
to –25, the maximum would be –10.
to –25, the maximum would be –10.• Minimum—Searches the entire model or the specified area of the model for the quantity's minimum value. This value is the least positive value, regardless of the magnitude of the value.
• Maximum Abs—Searches the entire model or the specified area of the model 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 temperature ranged from –10 to –25, the maximum absolute value would be –25. This option appears only if you select Temperature as the quantity.
to –25, the maximum absolute value would be –25. This option appears only if you select Temperature as the quantity.• Range—Calculates the difference between the maximum and the minimum temperatures in the model or the specified area of the model. This option appears only if you select Temperature as the quantity.
