HOOD MESHING FOR STRUCTURAL ANALYSIS USING ANSA

HOOD MESHING FOR STRUCTURAL ANALYSIS USING ANSA

• The objective of this project is to perform meshing for a given hood model using ansa.the model is cleaned and checked for errors,then using the given element size is meshed accordingly.
• For meshing process ,the following steps are necessary

1. Geometry checks
2. assign pid for inner and outer hood
3. Midsurface has to taken
4. assign quality criteria
5. meshing

OUTER HOOD MODEL

INNER HOOD MODEL

The separate pid set up has to make for inner hood and outer hood

1.Geometry checks

• Import the Hood model.igs file
• set the perimeter length and macros to 5mm under mesh module.
• give topo for the entire component and check usually for any abnormal faces.
• check the geometry for errors with check manager and correct the errors like triple cons,cracked faces,single cons.
• auto -fix the geometry.

2.ASSIGNING PIDS

3.Midsurface

• we can create mid surface using the offset option or the midsurface option.For now we can use the offset option.

4.Quality criteria

• we have to assign the given quality criteria for meshing the model.

5.Meshing

• The required element size for the whole geometry is 5mm.the option best mesh is used for meshing and after that reconstruct ,smooth split,swap option used to remove off elements.
