In the doe.dat file, the <criteria> section is used to control the display of the Quality Criteria in the DOE builder. In the parametric.dat file, this section controls the display of the Comparison Criteria.
For each molding process, mesh type and analysis sequence, the <criteria> section defines:
<process name="Thermoplastics Injection Molding" mesh="midplane" anal="Warp"> <default_rlt_list>6250 6252 6254 6256 6258 6260</default_rlt_list> <criterion_group visibility_switch_tcode="10000, 612, 0, OR, 10000, 612, 1, OR, 10000, 612, 2"> <name xml:lang="en">Deflection, all effects</name> <criterion id="110537" goal="minimize" weight="1.0" type="standard_deviation" component="norm"> <name xml:lang="en">Deflection, all effects Deflection</name> <result id="6250"/> <description xml:lang="en">The Deflection, all effects Deflection result is evaluated. The goal is to minimize the variation in the deflection. The lower the deflection variation the higher the part quality.</description> </criterion> ... <criterion id="130205" goal="minimize" weight="1.0"> <name xml:lang="en">Clamp force</name> <message id="41300" instance="1" item="1"/> <description xml:lang="en">The Maximum clamp force - during filling result from the Analysis log is evaluated. The goal is to minimize the clamp force. The lower the clamp force, the higher the quality. </description> </criterion> </criterion_group> ... </process>
where
<default_rlt_list> - controls the list of contour results. This type of result is applied directly to the original part, and is, therefore, most interesting for deflection results.
<criterion_group> - creates groups in the builder criteria trees.
visibility_switch_tcode - limits what is displayed in the builders, based on your selection in the Process Settings.
<criterion> - defines the Quality criterion or Comparison criterion for the purpose of the optimization.
id - is a unique quality identifier in the file.
type - defines how the large number of values linked to a standard result are condensed into a single meaningful criterion value. For example, type defines how the Fill time values attached to each of the model nodes is condensed into a single quality value. Options include minimum, maximum, range, average, and standard_deviation.
component - is additional processing information required for vector based results. The choices are X, Y, Z, or norm.
goal - is only available for DOE analyses, and determines the information that is output for a specific quality criterion during a DOE Variable Responses analysis. The choice is either minimize or maximize. This value is calculated by the DOE solver from an interpolated equation of the second degree, the response surface. The calculation includes the processed results of each single analysis run during the DOE analysis for that particular quality.
weight - is the default value of weight displayed for the criteria, and is used during a DOE Variable influences then responses analysis to build a hybrid criterion and to filter out the variables with the least influences, before running the analysis of responses.
There are two types of standard criteria:
id - defines either the result id, found in the result.dat file, or the message id found in the cmmesage.dat file.
instance - available only for message criteria, and defines which instance of the message will be selected. A specific message may be repeated many times in the log. Select "0" for last, "1" for first, etc.
item - available only for message criteria, and defines which item from the message to recover. A message can display many values, for example:
MSCD 4221 8 0 0 0 0 0 5 Residual stress model with CRIMS for Crystallization model coefficients: A1 = %11.4G A2 = %11.4G A3 = %11.4G A4 = %11.4G A5 = %11.4G A6 = %11.4G ,0,1 ,0,2 ,0,3 ,0,4 ,0,5 ,0,6
