Tool Test-2

Tool Test 2 (Solid meshing of Intake Manifold ANSA )

Aim: For the given intake manifold component, check the geometrical errors and meshing the surface with the given 2D element quality critera as mentioned below.

2D Quality critera:

Target or average length: 3

S.No	Quality criteria	Value
1.	Max length	5
2.	Minimum length	1

3D Quality criteria

Model:

When to use 3D elements

We use 3D elements when all of the dimension are comparable ( x-y-z)

Element shape: Tetra, Penta, hex, pyramid

Additional data from the user: nothing

Element type: Solid

DOF for solid elements:

Solid elements only have 3 translation DOF (Degree of freedom), no rotational DOF

Tetra-Meshing Technique:

There are two method of tetra meshing

1. Automatic Mesh: This approach is limited to simple geometries and pre-requisite is for error free CAD model. User has to just select the volume and software automatically carried out meshing as per specified element length, quality criteria.

Advantages: Very quick, no meshing effort

Disadvantages: Result in very high number of nodes and elements, There, is no control on mesh flow lines and specific meh pattern requirement (like bolted, welded joint or contact surface simulation)

2. 2D tia to 3D tetra Most commonly used method. Quad or tria meshing is carried out on all the outer surface of the geometry, quads split into trias and then converted into tetras.
