Project-2-Meshing of Door Inner Panel Challenge
Aim:Generating the midsurface and geometry clean up on the given component and creating the mesh with low tria concentration and proper mesh flow .
PROCEDURE:
- Download the model from the project assignment.
- Check the format of the model given. And import the model by selecting the proper format.

- Check the model if any other component present in that. If any present of other component in the given separate it by using the organize tool.
- For that go to MAIN MENU TOOL > TOOLS > ORGANIZE > COLLECTOR > ELEMENTS > NEW COMP IN DEST COMP > MOVE.

- Check the model if you find complex shape divide the model into 4 number of parts.
- Now take the mid surface one by one. If possible, take mid surface by automatic mid surfacing.
- For that go to GEOM > MID SURFACE > EXTRACTION OPTIONS > SKIN OFFSET > AUTO EXTRACTION > SELECT THE SURFACE > EXTRACT.
- Check the mid with parent component if its given good we can continue. But I found wrong mid.
- So, I went with manual mid surface for that go to GEOM > SURFACE EDIT > OFFSET > SELECT THE SURFACE > DUPLICATE > MAKE CURRENT AS REQUIRED > GIVE OFFSET DISTANCE > OFFSET.
- And some parts like ribs which we can take mid very easily auto mid by selecting two surfaces.
- For that GEOM > MID SURFACE > AUTO MID SURFACE = FINAL EDIT TOOLS > SELECT THE SURFACE > EXTRACT.

- If we observe the ribs not connected to the main mid surface. So, we have to extend to the main surface.
- For that go to GEOM > SURFACE EDIT > EXTEND > SELECT THE EDGE > SELECT THE SURFACE TO BE EXTENDED > EXTEND.
- Complete the model by taking the mid surface by using manual or auto mid tools.
- Before meshing it always preferred to give the quality criteria. To give quality criteria to MANU BAR > PREFERENCE > CRITERIA FILE SETTING > CHANGE THE VALUES OF QUALITY PARAMETERS ACCORDING TO THE REQUIRED > APPLY > OK.

- Now go to 2D > AUTO MESH > SELECT THE SURFACE > ELEMENT SIZE =5 > TYPE = MIXED > MESH.
- Now change element colour mode to by element quality. Here we can see how many numbers of elements are failing due to parameters.
- I have observed the many elements are failing due to quality.
- We have best option to correct most of the element quality with help of mesh rebuild.
- For that go to 2D > REBUILD MESH > SELECT THE ELEMENTS > REBUILD.
- Go to 2D > QUALITYINDEX > CLEANUP TOOLS > use the tools like PLACE NODE, ELEMENT OPTIMIZE, DRAG TRIA ELEMENT and SWAP EDGE.

- we can also use some extend option to join the mesh elements for the ribs.
- Before using this option, we should mesh on both surfaces.
- Now go to 2D > MESH EDIT > IMPRINT > SOURCE= NODE LIST > SELECT THE NODES > DESTINATION = ELEMENTS > REMAIN = DESTINATION > CREATE.
- It’s time to assign the thickness property to mesh. We can directly go for auto mesh thickness assign.
- MANU BAR > MESH > ASSIGN > MID MESH THICKNESS > SOLID MESH = COMPONENT > MID MESH > THICKNESS > THICKNESS OUTPUT > PROPERTY ON COMPONENTS > CALCULATE THICKNESS.
- We could see that it has not given property thickness properly so, we have to change the thickness of elements.
- For that go to TOOLS > ORGANIZE > COLLECTORS > SELECT THE ELEMENTS (which we want to change) > SELECT THE COMPONENT (which has the proper thickness) >

- Save the file.
LEARNING OUTCOMES:
- use of mesh edit option like extendeding the mesh upto the surface.
- Assign of auto thickness and correcting the thickness.
- taking the mid surface for complex shapes
