SMS:2D Mesh Nodestrings Menu: Difference between revisions

Revision as of 17:57, 13 December 2013

The Nodestrings Menu includes the following commands:

Command	Description
Options	breakline options
Force Breaklines	Force element edges to follow the selected nodestring
Smooth	Smooth the mesh boundary along the path of a selected nodestring by moving midside nodes. Only used for quadratic elements.
Renumber Nodestrings	Renumbers the nodestrings starting with an id of 1.
Merge	Merge selected nodestrings to form a single nodestring. Available if more than one nodestring is selected.
Split	Split a single nodestring into multiple nodestrings at the selected mesh node. Available if a mesh node is selected.
Reverse Direction	Reverse the direction of selected nodestrings. Selecting a nodestring causes the direction arrows to be displayed and can be used to verify the nodestring direction.

Mesh Nodestring Options dialog

Controls how breaklines are processed.

Insert new nodes – Triangles intersected by the breakline are modified by adding new nodes at necessary locations to ensure that the edges of the triangles will conform to the breakline. The elevations of the new nodes are based on a linear interpolation of the breakline segments. The locations of the new nodes are determined in such a way that the Delauney criterion is satisfied.
Swap element edges – Triangles intersected by the breakline are modified by swapping element edges to ensure that the edges of the triangles will conform to the breakline.
