Project - 2 - Meshing on the suspension Assembly
Aim: For the given assembly, check for the geometrical errors and mesh with the given element Quality criteria. Assign thickness for the midsurfaces after meshing the component. Use Appropriate connections to connect the component as suggested and perform the Symmetry command to reflect the half-finished model to the other side.
QUALITY PARAMETERS:
These are the following quality criterion required to be followed in this project:
Procedure:
First, import the CAD model into the ANSA interface. Proceed for a geometry check and fix all the topological errors. Once we have fixed all errors we can segregate different parts under property ID so as to proceed part by part which helps to expedite the process of pre-processing
Quality parameter and Mesh parameter setup as per the requirements given
Set the quality and mesh parameters as given for Tire and Rim. (ortho Tria & Tria)
Set the quality and mesh parameter as given for all other components (Tria and ortho Tria)
set the quality parameter for components with a uniform thickness of less than 5mm
Set the solid quality parameter for the Tetra element collapse value to 0.2
Mid-surface extraction of the components with a uniform thickness of less than 5 mm
Since only 3 parts have a length of less than 5 mm(uniform thickness) the midsurface extraction is undergone.
Mesh correction and Shell meshing:
1) Rim and Tyre
2) Ball joint knuckle, ball joint pin, and steering knuckle 
3) Brake Disc and Wheel Hub
4) Upper Strut mount and Brake calliper
5) Pendulum Bar and Shock absorber
6) Car Frame and Wishbone
7) Tie Rods and Sway bar
8) Bush Links Mounting and connectors
3D mesh generation and Volume definition for other than mid-surfaced components.
Define their volume and generated Tetra elements through the volume. The part should be properly meshed and closed. The part should not contain any overlapping surface. Define them one by one and set different PID types Solid.
There are some section views illustrating Tetra solid elements inside the volume
Implementation of connections in required areas.
There are specific areas that need connections representing bolt, weld, and rigid connections.
Final Result:
The meshing process is completed and the final model is obtained as shown below
Conclusion: The challenge was successfully completed as per the given requirement.
