Report Submitted by YASHVANTH KUMAR S K

AIM:

For the given component 2D meshing on the instrumental pannel check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned.

OBJECTIVE:

Geometry check & Topological error clean up

Mid surface generation

Meshing the geometry

QUALITY CRITERIA:

ABSTRACT:

In this project, the instrument panel of the car dashboard is taken for the pre-processing stage of CAE. The pre-processing of this model is done using BETA-CAE-ANSA software. The mid surface extraction and shell meshing are mainly demonstrated here in this project. Also, the good practices to be followed during shell meshing are discussed here.

METHODOLOGY:

Import geometry.

Topological error cleanup

Mid-surface extraction

Quality criterion setup

Meshing and Mesh improvement

PROCEDURE:

Step 1 :- Import model

Firstly, we need to import the model and study geometry and perform TOPO

Step 2 :- Geometry cleanup

After importing geometry into the ANSA environment we observe many topological errors while doing the geometry check-up as shown below.

Few area are not able to clear the geometry error those area to be cleared manually with appropriate method.

Next, we have to measure the thickness throughout the part & assure uniform thickness across the entire part. If thickness changes are observed then all alike thickness has to be kept under a separated property ID.

Step 3 :- Mid Surface

After measuring the thickness, it has the variable thickness so decided to go with Mid surfaces with casting method. And assigned the given quality criteria.

Step 4:- Correction of mid surface.

Correction of mid surface by align manager as we are seeing the surface which created are not align with original CAD model.

Using fallowing step

1. Mid-surface / Allign manager/ Edit / and select the surface whichever need to correct.

2. curve / Create curve – and fill the material using shell mesh / Fill by selecting the curve.

Step 5:- Achieving given quality criteria.

Using reconstruct, improve, fix quality, move, split, paste command to achieved the above said quality criteria.

Step 6:- Assigning Thickness.

Using Grid/thickness assigned the thickness of using 0.3 steps and check in property.

CONCLUSION:

The panel had been captured quite a well-using shell meshMost of the areas of fillets are captured using mid surface / casting options. The mesh flow is smooth nearer to target length and within the quality parameter.
