Tool Test-2

Tool test-2

For the given Intake Manifold component, check for the geometrical errors and mesh the Surfaces with the given 2D element Quality criterias given below. 

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

PROCEDURE:

STEP 1: Import

After given model  is imported, it is clear that there are many topological errors in the model.

STEP 2: Geometry Cleanup

Once imported, to remove the topological issues, Topo option is used

It is observed that most of the errors are removed by topo tool.

STEP 3: Geometry Check

From geometry check there are no errors in the model.

STEP 4: Orientation

STEP 5: DeFeaturing

Smaller areas less than 1mm is defeatured inorder to obtain mesh with elements following the quality criteria.

STEP 6: SHELL Meshing

Initially, hole sections and circular sections are meshed using spot mesh option with element type as ortho tria.

Plain surfaces are meshd using tria elements and the whole model surfaces are meshed.

Shell elements violating quality criteria are cleared using reconstruct and Num+/- tool.

STEP 7: Define Volume

STEP 8: Volumetric Meshing

Tetra FEM option is used and volume defined is selected to produce the volumetric mesh

Volume mesh obtaine with 5134 elements violating criteria.

Under solids Quality criteria, min and max length was turned on, which was unnecessary and removed.

STEP 9: View in Volumes mode

STEp 10: Alignment

Alignment of nodes are done to avoid kinks and drops on the solid mesh of the model

CONCLUSION:

Given Intake manifold was performed with the follwoing actions:

• Geometry Checkup and Clean
• Shell mesh using othro tria and tria elements under specified qualtiy criteria
• Defining volume
• Performing volumteric meshing of the model using TetraFEM option
• Correction in alignment of the Volume mesh
