Week 3 - 2D meshing for sheet metal

AIM:For the given Hood model, Take the mid surface for all the components after checking the geometrical errors and mesh the mid surface with the given element Quality criteria

objective: to get model fe of the sheet metal component using mid suraceing operations

procedure: 1) Import the geomery in ansa , set cons resolution to 1mm.

2) in topo module use the use middle / offset to extract mid surface.

3)For offsetting the surface use measure the sheet thickness the offset the surface and in pid assign thickness to offestted surfaces.

4) do the topo optimisation for the mid surfaces.remove unnecesary cons.

5) for inner panel and hood perform planar cut and delete hald of the panel.

6) set the con resution in mesh module to 5 mm. set quality criteria.

7) make small cut to make recatngle to avoid tria in mesh

8) use best option to mesh the components

9) after meshing use transform copy option to perfom symmetry option . use 3 point plane.

10) use topo to join, in case if topo isnt performing use prject hot point to project hot point to other surace then perform topo.

conclusion: by performing this i have leart about mid surfacing and shell meshing of sheet metal parts.
