Assignment 1-2D Meshing Challenge

AIM:

To extract mid surfaces and to mesh them with the given quality criteria

given there are 3 models , for which we have to extract the mid surfaces

PROCEDURE:

• Upload the model or geometry that is given
• clean up the geometry
• extraxt the mid surface by MIDSURFACE command
• else, offset it as required for the model

make the model as midsurface ready

MODEL1:

• clean up the geometry
• extraxt the mid surface by MIDSURFACE command
• AS IT a simple model, midsurface is easily extracred from the surface

• as shown extraced midsurfaces,are to be made meshing ready
• featred lines are to be toggled where ever necessery
• mesh with set in quality criteria
• 
• apply the property and thickness to the meshed mid
• check for the free edges in the FE model
• if there are free edged , join them using the commands

model 2:

• the procedure follows as, same as model 1

• mesh the surfaces QC
• these are as shown below, along with the free edges and thick ness

MODEL3:

• it ia little complex one, having cirvatures, fillets with in it
• geometry is to be made ready, chaeck for the unnecessery points replace them with bse points
• extracted mid is to be care fully , toggled for the meshing
• these are as shown

meshing:

CONCLUSION:

• Creating mid surfaces from various methods is seen, based on the method, time taken and complexith of shapes we have to choose a method to extract mid
• maitining good mesh with in the element quality having even density
• assigning properties, materials is known in detail
