Description

Fills gaps in FE from elements selected on both sides of the gap.

Inputs

mode

0 - The input elements are the shell elements defining the boundary, and the gap boundaries are.

1 - The input elements are 1D elements defining directly the gap boundaries.

mark_id1

The mark ID containing the elements at the first boundary. Valid values are 1 and 2.

mark_id2

The mark ID containing the elements at the second boundary. Valid values are 1 and 2.

max_width

Maximum allowed gap width to be filled.

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.
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 fi.
DefineMaxWidth: 0 - Ignore max_width for gap filling.; 1 - Consider max_width for gap 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 gaps less than 100 between elements in comps 1 and 5, including remeshing:

*createmark elems 1 "by comp id" 1
*createmark elems 2 "by comp id" 5
*createstringarray 2 "Remesh: 1" "DefineMaxWidth: 1"
*fill_fe_gaps_elems 0 1 2 100.0 1 2

To fill gaps between features of two sets of elements using a gap width of 50, and using guide node pairs for correct triangulation:

*createmark elems 1 12-18 55-100
*createmark elems 2 45-50 101-166
*createstringarray 4 "ByFeature:1" "Remesh:0" "DefineMaxWidth:1" "AdjacentComp:1" "GuideNodePairs:17 18 25 66"
*fill_fe_gaps_elems 0 1 2 10 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
}
