Tool Test-2

Given Model

• Geometry check

• Given Quality criteria

2D element Quality criteria

S.NO.	Quality Criteria	Value
1.)	Target/Average length	3
2.)	Minimum Length	1
3.)	Maximum Length	5

Quality after Volume meshing.

S.NO.	Quality Criteria	Value
1.)	Tet collapse	0.2

• Mesh

Here we use 2 methods for mesh first we use batch mesh or Auto mesh option. We know batch mesh generally used for non-uniform thickness model. Like casted or moulded components.

Command : Batch Mesh Manager >> new >> Meshing Scenario >> Double click on Meshing_Scenario >> select Intake Manifold.igs >> ok >> Double click on Default_Session >>selecting Mesh Parameters and Quality Criteria >> Run

Mesh result:

Manual method:

Procedure/ Steps

• Geometry check
• Setting quality criteria and mesh parameters manually.

• Start 2D meshing by using command: Classic Mesh >> Mesh Generation >> Spot Mesh >> Option List (Ortho tria – for curved surface and Normal tria for Flat surface) >> select area >> hit middle mouse click
• First, we select holes and curve surfaces and then after we select flat surface and we get 2D mesh. Some elements are failing quality criteria and we fix them.

3D mesh

• setting Solid quality criteria

Command: V.Mesh >> Volumes >> Define >> Selected >> Ok >> Window selection >> middle mouse click.

Volumes >> List >> Right click on the solid property >> click remesh (option and select the volume type as) >> tetra rapid to obtain the volume mesh

Finally we get 3D mesh

Ansa file name: Intake Manifold_2nd attempt.igs

Given Time : 5hrs.

Time taken by Me:- 6hrs.

CONCLUSION :

In both the method some elements are failing in Tet collapse some of them fixed by auto fix option and some of the fix manually.
