Project 2 - 2D meshing on the instrumental Panel

Introduction:

1. Objective:

The objective of this analysis is to perform meshing on a IP Console component using ANSA and pass all quality criteria, geometry check and proper mesh flow.

2. Procedure:

Import CAD Model

· The CAD geometry was imported into ANSA using .iges format.

Check Geometry

· Removing all single cons available in model

· If the faces is deleted, creating new faces by selecting fitted option

· Removing attached two surfaces, by doing topo

· Orient is used to orient all surfaces into one direction

· If there is unchecked faces it should be cleared

· Finally Status shows 100% correct

· After doing these correction, model shown as below

3. Mid Surface Generation

· I have done Auto Mid surface generation for this model

· And finally Mid casting, we should assign minimum thickness, target element length, give input as handle as single solid

· Capturing Dog houses Using Alin Manager tool

· By using Area, perimeters, direct options, as shown below

· Finaly Mid surface is done for three cases.

4. Assigning Tickness for Geometry

· By doing Set PID , we can assign thickness for the mid surface and parent geometry

· By doing this, the separate property ID formed in PSHELL

5. Meshing Process

· Setup the elemental length

· Edge of the hole should be parallel to the perimeter for proper mesh flow

· The hole should only having even number of edges

· check the fillets are passing to my length criteria, if not do defeaturing

· Assign the Quality criteria as given, as shown below

· Assign the mesh parameters like Target length, min length

6. Meshing

· A 2D surface mesh was first created using quad elements, This ensured a higher quality mesh for the simulation.

· First mesh is done on critical feature, fillet

· Maximum tria element should be removed.

· There is a associate between mesh and surface

· When we move or remove mesh the associative from the geometry

· The mesh behaves independent of the geometry

· Mesh quality is improved using mesh tools in Classic Mesh Tap

· Like Elements(split, swap, join ), Gride(Move, Paste), perimeter(Num+/-) etc

· Auto Mid And Mesh has taken 34min to complete

· Finally best mesh is achieved.

7. Learing outcomes;

ü ANSA Tools

ü Geometry cleanup for Ip console component

ü Extract Mid surface of varying thickness use different comments

ü Capturing feature using Align manager tool

ü Capturing mid for Solid Hollow component

ü Mesh the console component with less tria concentration and proper mesh flow.

8. Conclusion

· In this report, the meshing process for the given CAD model in ANSA was successfully done.

· Meshing is done in proper mesh flow

· In this meshing process for the plastic component, ANSA great to create a high-quality mesh suitable for further Finite Element Analysis.
