| Contact_weight Weighting for contact elements |
Usage |
||||
|
||||
Description |
||||
Weighting for contact elements (default 0.2)
|
| Element_weight Weighting factor for number of element nodes |
Usage |
||||
|
||||
Description |
||||
Weighting factor for number of element nodes ( Welem (default 0.7)). This weighting factor scales the element weight based on the number of nodes used by each element type ( nelem ). It therefore has no influence if the model uses a single element type. If mixed element types are used then the default element weight ( Wdef) is set using the default number of nodes ( ndef a triangle (2-D) with 3-nodes or a tetrahedra (3-D) with 4-nodes), so that the weighting for elements with different number of nodes is then:
W = Wdef + ( nelem - ndef) * Welem

| Write_domains_and_exit Flag to indicate whether to exit just after creating the parallel files |
Usage |
||||

|
| Number_domains_per_node Number of domains for each cluster node |
Usage |
||||
|
||||
Description |
||||
Number of domains on each cluster node. Only required for large models that require large amounts of memory. If Number_domains_per_node is specified then the number of domains simulataneously initialised will be defined by Number_simultaneous_domains to reduce peak memory requirements.
|
| Number_simultaneous_domains Number of domains for simultaneous initialisation |
Usage |
||||
|
||||
Description |
||||
Number of domains on each cluster node (default 10)
