Project 1 - 2D meshing on the instrumental Panel

Procedure :- 

Step 1 :- Import the model.

File -open -select the model -open.

 

Step 2 :- Checks for geometry.

geometry -checks -execute.

 

Step 3 :- Measuring the thickness .

 

 

Step 4:- giving length 

Step 5 :-Assigning Quality criteria to the model.

 

 

Step 6 :-Assigning Quality parameters .

 

 

Step 7 :- Generating  Meshing (Tria)

1.1) Generating meshing Non Uniform thickness components

 

 

1.2) Reconstruction

 

 

1.3)  Generated  Mesh

 

 

1.4)  Volume meshing of all Non Uniform thickness components

Define the volume :

voume mesh -volumes -define -visible-ok 

 

Defined Volume 

 

1.5) Generating tera-rapid unstructured mesh.

vomume mesh -unstructured mesh -tetra-rapid -select the volume - ok.

 

 

 

1.6) Generated volume mesh.

 

 

 

2 ) Mid surfacing of Uniform thickness part which has thickness less than 5 mm

 

2.1) Taking mid surface 

Topo -Faces -Mid surface - skin.

 

2.2) Generated Mid surface .

 

2.3 ) Assigngn Quality  Critera 

 

2.4) Generating Mesh 

 

 

Smoothig .

 

2.5)Generating Mid surface using  offset .

 

2.6) mid surface generated .

 

 

2.7) Meshing the  mid surface using Mixed Element type.

 

3)Surface Meshing of Tyre and Rim 

3.1)Mesh parameters

 

3.2)Quality Parameters.

 

3.3)Generating Mesh (Tria)

classic mesh-mesh generation -spot mesh -select the surface -mesh.

 

 

3.4)Generating Volume Mesh.

voume mesh -volumes -define -visible-Defined Volume -tetra Rapid 

 

3.5)Quality poarameters for volume mesh.

tet collapse -0.2

 Tet collapse failure

 

 

 

Passes Tet collapse .

Tyre

 

Rim

 

4)Modeling suspension Spring.

 

4.1) Creating Curve .

Topo- Curves -middle -selec t the two lines -create mid curve.

 

4.2) Connect the curves into one curve .

Topo- Curves-Multi -select all curves -ok

 

4.3)Generating 1D elements

Create 3D node :_  Topo -Points - COG -selelt the spring 

 

Nastran - Cbar - curve box -select the spring -select the 3D Points

specify the element lenght -create new property -Give radius -Area

 

 

Created 1D element .

 

 

Line elemental crossection as solid

 

 

Meshing Completed

 

 

5) Creating Connectors.

 

RBE2 with 2 Nodes

RBE2 Connected.

 

 

 

RBE2 with Many Nodes .

 

Created Cluster RBE2 

 

 

 6)Reflection

 

 

Tranfrom -copy -select the entites -summetry -mirror -ok

Final Model :- 

Result :- Given assembly, checked for the geometrical errors and mesh with the given element Quality criteria.After meshed thec component  thickness has to be assigned for mid surfaces. Use tetra elements to model non-uniform thickness components. Also use Appropriate connections to connect the component an d performed  Symmetry command to reflect the half finished model to the other side
