Assignment 1-2D Meshing Challenge

Aim:

To clean geometry ,Extract mid surface ,clear issues and assign the property.

Given CAD:

Part 1:

Part 2:

Part 3:

Procedure:

part 1:

¬ Inport the CAD file into the hypermesh software.

Geometry clean up:

¬ First clean geometry where it needed.

¬ Topo modo on check wheather the red line or yellow line available .

¬Check the missing surfacce.

¬There are some surface missing using the fillet surf option to clear that.

¬ some are in red lines clear it using the toggle option.

Extract Mid surface:

¬ Then extract the mid surface using suto mid sutrface option.

¬ Geometry - midsurface - automidsurface - select surface.

¬Etract the midsurface.

Defeature:

¬Defeature means ignore the fillet which have min length of quality issues.

¬

¬ neglect the hole which have below the 5mm dia .

Generate Mesh:

¬Then generate the mesh before that assign the quality criteria.

¬Set the min length as 3.5mm

¬Set the max length as 7mm

¬Target length as 5mm

¬Then start meshing area by area.

¬ Go to 2D-automesh - set target lenghth as 5.

¬Meshing is completed.

¬check the quality issues as well.

¬Clear all the quality issues.

Assign the thickness:

¬Next step to assign the thickness.

¬Create property card , right click on the tab bar and select the proerty.

¬ The assign the thickness right click on the midusrface.

¬ select assign option choose the T = 0.91 property .

¬ Then Tool bar - 2d Detail representation option.

Part 2:

¬ Part 2 is similar to the part1 .

¬ Doing the same process what done in part1 .
