If MAT252Strategy = 2 is used, a clustering pipeline is invoked as described in Output: New *PART and *MAT252 Cards. Below, the additional commands are listed and explained, which are mandatory for MAT252Strategy = 2.
| NumberOfBuckets = INT | Number of buckets for clustering the elements. If every bucket contains at least one element, the number of newly created parts equals NumberOfBuckets. Otherwise, *PART cards with no elements are deleted from the input deck. |
| StartingPartID = INT | Starting ID for the new parts resulting from the clustering of the elements. |
| SecID = INT | Each newly created *PART keyword requires the definition of a material ID and a section ID. While the material IDs are assigned to the parts by Envyo, you must define the section IDs. Currently, the section ID provided in this command is assigned to every new part. |
| StartingMatID = INT | Starting ID for the new *MAT252 keywords. |
| AddMatCohesiveParameters = DOUBLE, DOUBLE, DOUBLE, DOUBLE | Adhesive materials, such as the *MAT252 model, are often used in conjunction with the *MAT_ADD_COHESIVE keyword, which is characterized by the following five parameters: PID, ROFLG, INTFAIL, THICK, UNIAX. The pard ID (PID) for the newly created parts is already generated via the Envyo application. The remaining four parameters are parsed from this command and use for all *MAT_ADD_COHESIVE keywords. |
| MAT252ClusteringDegreeOfCureStartValue = INT | In addition to the number of buckets, you are required to provide a starting value for the DoC-range which is divided into buckets. In the current implementation start value of the range is by the command MAT252_Clustering_DegreeOfCureStartValue and the end value is DoC=1.0. Typically, the value pgel is used for this command, from which the solidification starts. However, if it is known a priori that all DoC value fall into range starting from much higher than pgel, other values can be used as well. Note that in all cases, an additional bucket is created that contains all elements in the DoC-range from 0.0 to start value set by you. |
