Week- 5 - Solid meshing

Objective: For the given component checcking the geometrical errors, and meshing the component for both in 2D and 3D meshing for surface and volume respectively

Procedure:

As, it is a solid meshing object the procedure will be different to the mid surface and mostly used for components having thickness greater than 5mm

• check for geometrical errors as it the main proceeding factor for 3D meshing
• go to mesh mode and define the length as 1mm
• set the mesh and paramatric values

note: set maximum and minium lenght parameters for2D ones i.e, for the surface meshing and set collapase for the 3D i.e, for the volumetric meshing

• mostly use orthotria for the surface mesing , even mostly in curved and complex surfacs
• tria can be used in the planner zones

• the surface mesh should be a closed one , it should be in defenetly closed as for the volume to be recognised
• now go th the volume mesh mode
• set the define by manual or as ANSA detects itself a closed volume and recognise as a volume
• set the property as Psolid the properties
• now, as the volume os defined we, can use tetra mesh i.e, 3Dmeshing
• we can use the terta rapied of tetra fem algorithms

Note: we can any type rapid or FEM it genetran defines the way of mesh generation and growth of the tetra components

The entire set up is done for the meshing and now generate the mesh, check for the collapase errors as you would have checked the minium and maximum legth errors in the mesh mose itself

• use boullion aperation and see the internal tetra meshing as show in in fg, to get the view of the mesh growth
• if collapse error are seen go to fix quality
• even the errors are not rectified go to mesh mode ane use MV operation which helps to change the orientatiom of the nodes in a tetra elemets

Also check for the surface deffects i.e, for both knicks and raised edges

• this can be cleared by usimg the smooth improve or by paste option
• paste option can be used the change the placement of the nodes in the tetra elements
• 

the entire ccomponent is as shown in th figure down

Note: be care full while givinig the orthotria and tria for surface as if mainly alters the growth of the tetra elements which leads to the collapsing
