Week- 8 - Solid meshing

PROJECT REPORT ON SOLID MESHING (Rear view mirror component)

AIM:- For the given Rear view mirror component, check for the geometrical errors and mesh the Surfaces with the given 2D element Quality criterias given below.

For the given geometry we have to set quality criteria and mesh parameter

Now first we have go for check geometry to eliminate all geometrical errors then goto further step

For that we have to follow the following step :-

First we have to do TOPO under topo module for the proper connections

1) After that we go to mesh module under this perimeter we select length option after left clicking on that option we select the whole model by midle mouse click we set a value 1 and click ok. By doing this in the geomtry the distance between any two nodes will be 1 unit

2) After that again we go to check >geometry>execute there are so many errors found one by one we resolve the errors and again go for check >geometry>execute and repeat this cycle until all the geometrical errors are eliminated

3) Now goto classical mesh module and perform spot mesh over the 2D surface classical mesh>mesh generation>spot mesh, under this spot mesh please check option list select ortho-Tria for fillets or feature Area and Tria for plane surface and after that perform reconstruction macro by macro

Here we perform spot meshing speratly for PID region one by one follow by reconstruction

4) After 2-D Meshing on the surface we are going for Volume mesh for that Define the Geometry for volume mesh goto volume mesh Deck>Volumes>Define, select volume and right click>Edit unstructured mesh>mesh with>tetra FEM do it one by one for all the auto detected volumes

5) After that goto volume mesh deck>Unstructured mesh>Tetra mesh select the whole by box selection press middle mouse button and volume mesh is created

Now observe the model carefully if any quality failure occure then correct it

Conclusion:- First we need to see the model carefully before doing any thin and create a path in mind how to proceed , then perform the similar kind of operations because in solid meshing we have to some techniques for better results without any complications
