Week - 7 - Checking and correcting the edges

AIM:

To check and correcting the edges.

OBJECTIVE:

• Create a code that displayed free and T edges for displayed elements.
• Free edge color red and T edge cyan.
• Except for edges, all other components must be made transparent.
• Also, temp nodes must be automatically created for “free nodes” for a tolerance value of 0.01.
• Also, create a code to turn off free edge display and restore the window to the way it was.
• Map these codes over a key and also create a tk widget for the same.

PROCEDURE:

Initially, the display is set to transparent mode using (*setdisplayattributes ) command.

Two Different functions were created to display Double cons and Triple cons.

• Elements displayed were selected using the (*createmark)command
• Then edges of the selected elements are shown using the (*findedges1) command for Free edges and T Connected edge the edge_type values are 0 and 1.
• Then component with name ^edges is renamed with "respective edge name " using (*setvalue) command
• temp nodes are created by marking the node using( *equivalence )with tolerance of 0.01 and (*nodemarkaddtempmark )

Syntax

• *setdisplayattributesstyle colortype

style Set to:

• 0 wire frame
• 1 hidden line
• 2 hidden line with mesh
• 3 hidden line with features
• 4 hidden line transparent

colortype Determines how the components are colored. The options are:

• 0 none
• 1 component color
• 2 assigned plots
• 3 contours
• *findedges1entity_type mark_id edge_type created_entity smooth break_angle

entity_type The entity types to find edges for. Valid values are comps and elements .mark_idThe mark ID containing the entities. Valid values are 1 and 2.

edge_type The type of edges to find:

• 0 - Free edges.
• 1 - T-connected edge

created_entity The entity type to create on the found edges:

• 0 - Plot elements
• 1 - Free lines

smooth The smoothing to use when created_entity is 1:

• 0 - No smoothing.
• 1 - Smooth the lines through the nodes.
• *equivalenceentity_type mark_id tolerance mode location numbering

entity_type The entity types to consider. Valid values are elems, comps and nodes.

mark_id The ID of the mark containing the input entities. Valid values are 1 and 2.

tolerance The tolerance used to find neighboring nodes to equivalence.modeOperating mode of the command:

• 0 - Preview found nodes.
• 1 - Equivalence found nodes.
• 3 - Place found nodes on user mark.

location Location of equivalenced nodes:

• 0 - Equivalence at the location of the node with the lowest ID.
• 1 - Equivalence at the location of the node with the highest ID.
• 2 - Equivalence at the midpoint of the two nodes.

numbering The numbering of the retained node:

• 0 - Retain the number of the node with the lowest ID.
• 1 - Retain the number of the node with the highest ID.

CODE:

OUTPUT:

RESULT:

• The code has been created and displayed for T-edges & fre elements.
• Free edge is indicated in colour red and T edge in cyan.
• Except for edges, all other components transparent.
• Temp nodes is created for “free nodes” for a tolerance value of 0.01.
• Code has been created to turn off free edge display and restore the window to the way it was.
• Maps has been coded over a key and tk widget is created for the same.
