Project 2 - 2D meshing on the instrumental Panel

OBJECTIVE

1. To fix all geometrical errors
2. To create Mid-surface 
3. To mesh with the given element Quality Criteria for the given instrumental Panel using casting.

PROCEDURE

1. Open the given instrumental Panel in ANSA by using File > Open

instrumental Panel

2 After that Go to Tool >Checks >Geometry for Cleanup.

3 As shown in screenshot, Checks Manager window click Execute to check any error occurred in instrumental Panel and fix the Error and Cleanup the Geometry.

Error in instrumental Panel

4. In the above screenshot, error has been occurred in the given instrumental Panel. Check the error showing in the Model and also tic mark on single cons.
5. When eliminating the error, Right Click on the error which is going to resolve and click Show only option.

Cleanup the Geometry

6. After that Click Execute in the Checks Manager and 100% Geometry Cleanup is now get.

CREATING MID-SURFACE:

1. After geometry Cleanup and Mid-surface has to be created for instrumental Panel.
2. initially to Measure thickness of the Component for Creating Mid-Surface. Go to Utilities > Measure Option
3. Click two nodes or cons to measure the thickness of the Component and Store the Measurement.
4. As there are more features in parent geomentry to reduce time we used auto mid surface casting option used to creat auto mid and auto mesh surface

           instrumental Panel Mid-Surface and mesh

MESHING:

1. For meshing Mid-Surface, set the given mesh Quality Criteria for the Component. 
2. For that follow Go Utilities >Quality Criteria Option and assign the given Quality Criteria Values.
3. After assigning the Quality Criteria for the Component, Go to Utilities >Mesh Parameters and assign the Average Value for Meshing.Mesh Parameters
4. Go to Mesh >Perimeters > Length Option and Select the whole good model to Mesh and enter the Value of Perimeter 5mm Length for Meshing   
5. Use Shell Mesh-->Reconstruct option to rearrange the Mesh and Use Shell Mesh >Smooth Option to refine Mesh lines equally within the Selected Surface and solving the Quality criteria issues.

                                                             Reconstruct mesh

                                                                     Smooth Mesh

1. Use Grids-->Paste and Elements >Split / Swap / Joint Option to eliminate or reduce the trias and get better mesh flow.
2. After meshing half surface now to eliminate quality criteria failure mesh we again smooth the mesh surrounding the failure occurrence.

                                          Quality criteria failure

Now using aling manager create middle for empty surface and plane those surface are not align with parent geomenty are aligened using align manager

                                    align manager

                  parent geomentry

                 mesh after aligned

                   mesh after aligned

similarly all other mesh suface also align with parent geomentry finally thickness assign to mesh surface

                                                                instrumental Panel Mesh

•  New things learn in this challenge are align manager and creating FE without surface
• Conclusion includes after finishing the challenge is if geomentry having more fetures then auto mid methode is preferable then mannual methode.
