Project 1 - 2D meshing on the instrumental Panel
objective:-
- clean up the given IP substrate models.
- meshing the models with the target element size 4mm.
- follow the given quality criteria and fix the criterian errors
procedure:-
Topo mode:-
- clean up the geometry.
- creating the mid surface for the model.
Mesh mode:-
- set the mesh length As 4mm.
- apply the mesh on the visible model.
- after mesh check the length between each node wether the length was correct or not.
- follow up the quality criteria with the following table and if any errors fix them

Step 1:-
- Geometry show below figure
- As we have done with the first step i,e we import cad model into ANSA pase as shown in the above figures.
- After that we check for the geometry as shown below figure
- we check the Geometry with the above parameters i,e single cons ,cracks,overlap faces,needle faces,triple cons,collapsed cons , unchecked faces if they are present we clear them.
- After doing the above step then we move to create the mid plane on the model by using the offset option under face option and after ANSA ask the midplane length and we give the length as half of the thickness and than give ok the mid plane was created after that ANSA ask whether the parent face is deleted or not and we give the input as NO.
- After completing the above steps the model is ready to mesh.
Step 2:-
- As we mentioned in the above mesh the model with the target element size 4mm and as shown below figures and before meshing the length was set to 4mm.
- below figures shows the models after meshing was done.
Step 3:-
- we move on to the satisfied the quality criteria with the as above mentioned conditions and below figure shows
- Quality criteria for the mesh parameters were checked mini. length,maxi. length,skewness,angle,Aspect cleared all the errors fixed them finally
- skewness is one of the primary quality measure for the mesh .skeweness determines how close to ideal a face or cell is
- minimum length which is given in the quality criteria parameters is a target which won't go below that
- maximum length which is given in the quality criteria parameters is a target which won't exceed than the maximum length given.
- cleared all the above quality criteria errors and fix them.
- After fix them below figures shows after satisfied the quality criteria.
Conclusion:-
- cleared all the topological errors and meshed for a length 4mm.
- Quality criteria satisfied for the given parameter.
- dissolve the some Quality criteria error.
