Mesh_parameter_data NUM=ival where ival is the data structure number |
Description |
Overview Mesh parameter data structure allows to define extra parameters used in mesh generation and adaptivity.
|
 | Smoothing_factor Smoothing factor for mesh generation |
Usage |

|
||||
Description |
||||
Defines a factor that controls the smoothness of transition in mesh size. The input value is the ratio of the large to the small element size for adjacent elements (hence the value is > 1). Larger values lead to more abrupt transitions whereas smaller values lead to more gradual transitions and will require more elements. Note that this parameter is also used during adaptivity.

Factor for local search for node insertion
|
| Exist_node_search_fact Factor for selecting an existing node during triangle insertion |
Usage |

Description |

Factor for selecting an existing node during triangle insertion
|
| Node_insert_perturb_fact Perturbation factor for node insertion |
Usage |

|
||||
Description |
||||
Perturbation factor for node insertion
|
| Fault_node_tol_2d Tolerance for neglecting nodes close to a facet for surfaces |
Usage |
||||
|
||||
Description |
||||
Tolerance for neglecting nodes close to a facet for surfaces in 2-D advancing front meshing. This factor is relevant if the mesh contains surfaces which are partially split or fully contain fault or fractures. In these cases, due to the minor overlaps that may arise due to enforcement of the contact condition using a penalty constraint. This factor is is only used for surfaces with no background grid; e.g. surfaces which are remeshed due to geometry changes; e.g. fault insertion. The default value is 0.02 and means that, when generating an element using a facet any node with normal distance closer than 0.02*Facet length will be neglected.
