Week- 5 - Solid meshing

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.

S.No	Quality Criteria	Value
1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	2

Use tetra elements to mesh the Volumes defined in the model and check for the below quality after Volume meshing.

S.No	Quality Criteria	Value
1	Tet collapse	0.2

Aim:-

1. Meshing 2D element, with min and max length quality criteria

2. meshing 3D element, collapse quality criteria.

3. check for the geometry error.

4. understanding the function of the tetra rapid, tetra fea.

PROCEDURE:-

1. Geometry check

2. Topo cleanup.

3. setting length of elements.

4. setting given quality criteria.

5. meshing the 2D model.

6. Meshing volume.

1. Geometry check:- geometry checkup done with ticked parameter listedd in following pictures

found issues with tripple cons crack and overlap and resolved by usin auto fix option.

we have obsorved 100 % ok for geometry check

a. model before any commands:-

b. Error observed while geometry checks:-

c. ensure zero errors:-

2. measuring the distance between the con:- measuring multiple location cons distance and matching with the target length of the element.

3. Defeauturing:- defeaturing the cons where meshing may fail with the smaller area of the model.

defeaturing the coons which is smaller than the min length of element 0.5

3. setting length of elements:- setting length of the macros to 1 as given in the quality criteria.

4. setting given quality criteria:- setting quality criteria given for the 2D and 3D element.

5. meshing the 2D model.:-

before meshing:-

after meshing:-

6. asigning the property identification to each meshed model:-

6. Meshing volume.

Learning Outcomes:-

1. learned solid tetra meshing

2. learned difference between ortho tria and tria.

3.learned tetra rapid and tetra fea

4. learned to check the min length and max length tet collapse .

5. practised well to get good solid surface finish quality

Conclusion:-

2D and 3D meshing of rear view mirror model completed with given criteria.
