Description

Fills FE holes by automatic or manual detection.

Inputs

mode
The mode to identify FE holes:
  • 0 - Do automatic hole detection using elements on mark_id.
  • 1 - Do manual hole detection using nodes on mark_id. The nodes should be part of a free boundary.
  • 2 - Do manual hole detection using given the closed 1D elements on mark_id.
mark_id
The mark ID containing either nodes or elements, based on mode type.
max_width
Maximum allowed hole width.
string_array
The string array ID that contains the additional input parameters. The string array is created using the *createstringarray command. This should always be set to 1.
Strings are indicated using the format "name: value". Valid strings are:
AdjacentComp
0 - Fill elements should be created in a new component.
1 - Fill elements should be created in the adjacent component.
2 - Fill elements should be created in the current component.
ByFeature
0 - Features should not be considered.
1 - Features should be considered.
CurvedFill
0 - Gaps are filled without taking into consideration the shape of adjacent elements.
1 - Gaps are filled taking into consideration the shape of adjacent elements, ensuring a smooth fill.
DefineMaxWidth
0 - Ignore max_width for hole filling.
1 - Consider max_width for hole filling.
GuideNodePairs
Specifies an optional list of node IDs in the form "M1 M2 N1 N2 O1 O2 ..." where (M1, M2), (N1, N2) and (O1, O2) are node pairs. These pairs are used to divide the gap to be filled into smaller loops. When provided, gaps are filled ensuring that the loops are split at the specified pairs. This aids in filling complex hole shapes by guiding the filling process correctly.
Remesh
0 - Fill elements should not be remeshed.
1 - Fill elements should be remeshed.
number_of_strings
Integer indicating the size (number of strings) in the string array created using *createstringarray.

Example

To fill the holes defined by the closed 1D elements 10-30, using a max width of 20.5, remeshing filled elements, and create the elements in the adjacent component:
*createmark elems 1 10-30
*createstringarray 3 "Remesh: 1" "AdjacentComp: 1" "DefineMaxWidth: 1"
*fill_fe_holes 2 1 20.5 1 3
To smoothly fill a feature hole using a set of nodes:
*createstringarray 4 "ByFeature:1" "Remesh:1" "DefineMaxWidth:0" "CurvedFill:1"
*createmark nodes 1 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
*fill_fe_holes 1 1 0 1 4
Fill a feature hole using guide pairs (12,18) and (25,13):
*createstringarray 3 "ByFeature:1" "Remesh: 0" "GuideNodePairs: 12 18 25 13"
*createmark nodes 1 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
*fill_fe_holes 1 1 0 1 4

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
