*aligntoedges

line_mark_id

The ID of the mark containing the lines to which to align FE edges to. Valid values are 1 and 2.

node_mark_id

The ID of the mark containing the node to align to lines. Valid values are 1 and 2.

After successful movement, this mark will be repopulated to contain nodes moved during the alignment.

string_array

The ID of the string array that contains the additional input parameters. The string array is created using the *createstringarray command. This should always be set to 1.

These are optional parameters that control the quality of the mesh around the edges. They are provided as name value params in the format "param_name:param_value".

The following parameters are supported:

FailureCountTolerance

The percentage local failure count tolerance at each edge to which nodes are being moved to. If the failure count of elements around the nodes being moved increases beyond this percent of the neighboring element count, the node movement will be rolled back. The default value is 0.1.

FailureIndexTolerance

The percentage local failure quality index tolerance at each edge to which nodes are being moved to. If the failure quality index of elements around the nodes being moved increases beyond this percent of the previous quality index of elements around these nodes, the node movement will be rolled back. The default value is 0.05.

GlobalFailureCountTolerance

The percentage global failure count tolerance to use for the mesh quality control after node movement to each edge. If the movement of nodes to an edge causes the global failure count of the mesh to increase beyond this percent of the total element count, the node movement will be rolled back. The default value is 0.1.

GlobalFailureIndexTolerance

The percentage global failure quality index tolerance to use for the mesh quality control after node movement to each edge. If after the movement of nodes to an edge, the global failure quality index of the mesh increases beyond this percent of the previous global quality index of elements in the model, the node movement will be rolled back. The default value is 0.05.

number_of_strings

Integer indicating the size (number of strings) of the string array created using *createstringarray.

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
