Hypermesh Radioss basic Componenets Geometry clean up 2D Mesh

Aim : To clean the geometry; Extract midsurface and create 2D mesh with given target length

Conditions

Target length : 5mm, min 3.5mm max 7mm.

Geometry Clean up

MidSurface and 2D Mesh

Procedure

1. First Geometry clean up is done using tools like toggle edge , circles with dia less than 5mm are disabled during mesh using unsplit surf command

2.Shortcuts like ;

F12 - Automesh

F11- Check elements panel

F3- Node Equivalence

F7- Align nodes/Node Operation

F6 - Combine or Split elements

Shift+F12 - Smooth

F4 - Distance between two nodes or points

F2 - Delete

Shift +F7 - Project line or point

Defeature command in Geometry was used to toggle edges at a time

Quik edit tool was used to for geometry clean up and after mesh operations

During the entire process tria elements were optimized

F10 - Check Mesh quality

Element Size was given as 5mm

3. The mesh was adjusted to obtain uniformity by using replace nodes or points tool and other tools

Results

Geometry clean up, mid surface and 2D mesh were generated for given drawings
