*trim_elems_by_multi_circular_hole
Trims shell elements with a circular hole and adds optional washer layers.
Syntax
*trim_elems_by_multi_circular_hole node_mark_id feature_angle string_array number_of_strings periphery_node_mark_id background_elem_mark_id rigid_spider
Type
HyperMesh Tcl Modify Command
Description
This command is used to trim elements with circular holes. Washer elements can optionally be added to the hole. Multiple holes can be handled at the same time.
Inputs
- node_mark_id
- The mark ID containing the nodes to use as the center of the holes. Valid values are 1 and 2.
- feature_angle
- This parameter is used to define mesh feature lines around holes and washer elements. The range should be (0, 180). It is usually set to 30.
- string_array
- The ID of the string array that contains the washer element information. The string array is created using the *createstringarray command. This should always be set to 1.
- number_of_strings
- Integer indicating the size (number of strings) in the string array created using *createstringarray.
- periphery_node_mark_id
- The output mark of periphery nodes generated on the hole. Valid values are 0, 1 and 2. If the value is set to 0, no periphery nodes are placed on the mark.
- background_elem_mark_id
- The output mark of background elements to be deleted in order to update the connectivity of the newly created elements and their neighbors. Valid values are 0, 1 and 2. If the value is set to 0, background elements are deleted and element connectivity is updated. Otherwise, the background elements are kept and placed on the mark.
- rigid_spider
- Valid values are 0, 1 and 2. If the value is set to 0, no rigid elements will be created inside the hole. If the value is set to 1, a single spider will be created inside the hole. If the value is set to 2, individual rigid elements will be created for periphery nodes.
Example
To create a hole around node 60 with a radius of 5, and 2 layers of uniform washer elements using a density of 8 and a width of 5.0:
*createmark nodes 1 60
*createstringarray 2 " hole_radius = 5.0 layer_number = 2 uniform_layers = 1 hole_density = 8" "1 5.0"
*trim_elems_by_multi_circular_hole 1 30 1 2 0 0 1
