G DRIVE LINK:https://drive.google.com/drive/u/0/folders/1ZSQynm4SPgr_raqT7iuoOtjYrrmSpTgG

Objective:

• To given model clean the geomentry error meshing the area both 2d and 3d(volume)mesh and achive the given QI
• Assign the proper thickness in mid surface
• Assign the appropriate connection between two parts

Given part

• The given part as sigle PID so we have to separate PID and parts

Sepatate parts and PID

Geomentry check for each parts

• Like wise we have to check the each parts

Identifying the less than 6mm for mid surface

• As per the measurement the flowing component are less than 6mm so, we take the mid for thease component
• LOWER CONTROL ARM,LOWER STRUT MOUNT,BEARING CONNECTOR

2d meshing

• For above menstion parts are taking manual mid surface

• INTRODUCTION OF VOLUME MESH
  • In ANSA, there are two modes for the generation of solid elements. The unstructured mesh creation algorithms like tetras and hexainterior mesh and the structured mesh algorithms like Map, Extrude, Layers, HexBlock etc... The first requires the definition of a closed Volume entity in advance in which the solid elements will be generated, whereas in the latter the Volume is defined automatically when the elements are created. The Volumes may be bounded by Macro Areas and/or FE-model shell elements.
  • All the functionality available for the handling and creation of solid elements is located under the
    MESH > VOLUME and under the separate Volume Mesh module

PROCEDURE TO START VOLUME MESH

• In order to perform the volume mesh we don't need the mid surface of the component
• check the geometry and clean the geomentry
• Once completing the topo area the move to shell mesh and mesh the tria or ortho tria i.e the curved area to mesh the ortho tria and the flaten surface area mesh the tria elements
• In 2d shell mesh we mainly constract the min.length,max.length,aspect ratio and warping only enough
• Then start the 3D volume mesh

Surface meshing to volume mesh

• For 3d volume meshing we perform the surface tria mesh for surface then convert surface to soild by using define volume

3d Meshing

• For volume meshing we use the tetra mesh for the all part
• FOR LIKE WE DO VOLUME MESHING FOR ALL ABOVE 6MM PARTS.

List of volume parts

Define the connection between various parts

• RBE CLASTER
• to connectin between various parts like disc hub and knuckle part,knuckle and brake caliper,lower strut and upper sturt RBE2 claster connection used
• Seam weld connection
• in one area we need the seam line connection

Complete the model

• to get the mirror of the model only it get complete the model sucessfully
• to get that goto>Transform [COPY]>sysmetry>default plane >apply>finish.

Result

• Through this project i learn the how mesh the 3d volume and clear the dips and kins error
• Through this assignment i learnt how to convert the shell mesh to 3d volume mesh
• In this assignment i learnt how to define volume and how to define propety
• in this assignment i learnt how to remove the tet collaspe and how achive the 100%QI
