Week- 5 - Solid meshing

AIM :

To mesh the rear view mirror component with given 2D element quality criteria and with out any geometrical errors.

OBJECTIVES:

• Use tetra elements to mesh the volume defined in the model.
• check for the below quality after meshing
• maintain good surface quality after volume meshing.

PROCEDURE:

• Export the gremetry
• filr>open
• there are 4 elements mesh each one of them using following procedure.

GEOMETRY CLEAN-UP

• check for proper attachment and continuity of the elements
• topomodule>topo
• topo>fine
• topo>orient for assign colour
• do cons resolution
• classic>perimeter>length as 1mm
• go for geometrical check
• check>geometry>execute.

GENERATING 2D MESH

• Assign perimeter length as target element length.
• set mesh parameter
• mesh parameter>tria mesh
• give quality criteria
• shell>minimum and maximum length.
• solid>collapse
• mesh flat surfaces using
• classic>mesh generation>best
• reconstruct for better mesh
• check for quality criterias.
• mesh rest of the areas using ortho mesh
• best>element type>ortho tria.

PRE VOLUME CHECK

• check for single cons and tripple cons.
• check for un-meshed areas
• go for intersection check
• check>penetration>intersection>execute.

VOLUME DEFENITION

• Volume mesh>volumes>define
• detect on>visible
• auto create the volume

GENERATING 3D MESH

• Volume mesh>un-structured mesh>tetra rapid
• using tetra rapid generate the 3d mesh
• check the 3d mesh.

RESULT:

• completed the mesh using tetra elements.
• maintaines the quality criteria
• completed the mesh without any geometrical errors.
