Week 8-3D Tetra Meshing Challenge

OBJECTIVE:1.Creating Tetramesh for a given housing model by 2D TO 3D conversion method

2.Creating Tetramesh for a given component by volume/direct tetra mesh method

3.Creating Tetramesh for a given component by volume/direct tetra mesh method

CAD model:Housing Model

Procedure:

Imort the model by selecting import<model
keep the graphics area in topomode then delete solids by selecting delete<solids<displayed<delete
quality parameters should be given by selecting Tools
then delete fillets which are having less then 2mm
geometry cleanup should be done by geometry clean up tools.
remove surfaces having less distance.
for meshing Go to 2D<automesh<Target element length 4<trias<surfaces<select displayed.2D mesh will be generated.
For quality check Goto Tool<check elements.adjust the failed elements till failed element become zero
Now we have to convert 2D mesh into 3d tetra mesh by selecting 3D<tetra mesh<select elements<displayed<then click on mesh
now we have to check the quality of 3D mesh.Go to tool <check elements<3D<tet collapse we have to work on the model upto tet collapse become zero.
same procedure have to be followed for model 2.

2.volume tetra method:

for this assembly we have to mesh 4 components individually.
Goto 3D<volume tetra<solids<select solids<2D type trias<3d type tetras<element order first or second<click on mesh
tetcollapse should be check as same in previous model.

Direct method:

Go to 3D <tetra mesh<components displayed<mesh.if the componet is not meshed then goto view<browsers<Hypermesh<utility<click on geometry mesh<select quick tetra mesh<then select components <clickcon proceed.
mesh size 4 and minimum edge size and minimum element size mesh type trias only<click on mesh
for quality check check for tet collapse same as discussed above.

CONCLUSSIONS:

Ship work like this
in your own course.
