create 3D meshing for the models housing and crank hub and chasis according to the parameters mentioned


For this week's challenge,  i will have to create 3D meshes for the models provided in the challenge according to the parameters mentioned.


For creating the 3d meshing we should have to create 2d elements first and after that by using 2d elements we can create 3d mesh by tetramesh option

and also we can create directly 3d meshing but its not agood practice and also we might not have control on the tetcollapse.

so firstly i imported the file.

for housing model created the tria elements with target length of 5mm and checked for the min and max element lengths .


and also TETCOLLAPSE means length of the tetra element 

so i used the element cleanup option and also shift+F4 option by translating the elements 

and after that for crank hub also done te same process .

and for chassis i cleared the geometrical errors by using defeature option and i checked before creating the mesh that where the min element length will fail,and i cleared taht geometriacal errors also.





From this challenge i have lerant about how to create tetra meshing and how to decrease the tet collapse failure for the tetra element.
