Week- 8 - Solid meshing

AIM-

to perform tetra element meshing for the rearview mirror component and there should be not and kinks dips on the surface of the component.

PROCEDURE-

1)import the model to ansa software, it consist of suppirting part ,a rotating ball , a mirror base, a mirror interior.

2) after importing the model,topology has been created between selected adjecent cons for performing topological condition between them. we need to check topological error anbd we have clear all error like single cons, triple cons, unchecked faces, needle faces, etc.

3) we next set the mesh parameter and quality criteria.

4) we have set an avrage length 1mm, we will select ortho tria and 1st order.

3D TETRAHEDRAL MESHING-

for 3D meshing , we hjave to define a volume for solid surface and after then we will have a mesh with tetra rapid mesh. after defining the volume, a new property id has been created. after then by using a tetra rapid we will mesh the volume. there should be no tetra collapse on the mesh, we have to eliminate then by using MV free command, we have to make sure that there should be no kinks and dips on the surface.

LEARNING OUTCOMES-

1) introduced to volume mesh.

2) learn to remove the collapse error in the volume mesh.

3) use a tria and ortho tria.

CONCLUSION-

we have obtained good result in a 3D tetrahedral meshing in the rearview mirror and feature capturing is done and used ortho tria element in the curved and file area.

COMPONENT NO-2 MORPHING.

AIM-

to morph the component by the vidio shown in week 8 vidios.

OBJECTIVE-

the practice component we need to understand the concept of the morphing , so what is morphing?

MORPHING-

1)it is the tool to change the shape of geometry or FE mesh to extent, and they it can proccesed for analysis.

2)first geometry has been clear with the geometry doing a topology and then checking the geomerty cehck and fixing the error with an auto fix option.

3) to morph the height of the top face with cylinder shape to change the height the box is created with the NEW option , selecting the ortho option in that we have a geometry that need to change by the shape.

4) so selecting the geomerty and box type ortho and then selecting the morph box.

5) selecting the point of the box that change the shape before changing the shape for the cylinder,first clicking the right click for the coordinatres . changing the y direction beacause to change the height ,moving by the coordinates the height will be incearsed.

6) beacause of the increase the height in the geomerty has some deform to check the geomerty , perfectly the length of geomery changes with 1mm perimeyter and macros.

7) for other geomerty changes,the same proccess is applied but with the for moving coordinates the x and y direction is selcted and also with z direction.

8) the whole geometry is also morphed shape changes . after the morphing the componet the box can be deleted by deleting.

RESULT AND CONCLUSION-

the whole geomerty shape is changed and learned that the geomerty of FE entities changes is changed by shape as per requirement by the industries.

diffrence betrween orignal geometry and change geomety.
