Cad model image attached below.
Procedure
first opened hypermesh.
imported the geometry,then created midsurface using the midsurface operation in geometry panel.
then created materials and properties,also assigned thickness of model(0.75) to the properties and also added materials and properties with components.
then looked missing surfaces,duplicated surfaces,fillets.rectified those kind of mistakes using replace points,delete surface,filler surface, toggle edges are in quick edit panel.some kind of missing surfaces filled with the help of ruled option in the surface operation which is in the geometry panel.
geometry cleanup was done by using above mentoined operatios.
next entered into the mesh,opened automesh option give the size of 5 units mixed mesh and selected surfaces, give the mesh.then increase and decrease the nodes for proper mesh flow,it repeated all the surfaces one by one.
mesh part over,then checked edges,normals,dependency,penetrations are in tools panel.
fianlly go for qualiy parameters area,went tools panel click check elements,set the values
aspect ratio=5
warping=15
skewness=45
min length =2
max length=8
taper=0.5
min angle of tria=20
max angle of tria=120
min angle of quads=45
max angle of quads=135.
then checked one bye one rectify the failed elements.for example check aspect raio,save failed and went mask option click the elements retrive,then gave mask reverse ,it helped only saw failed elements then gave unmask adjacent.all failed elements are rectified unmasked all.
repeated the same operations all quality parameters
Quality index also used to passing quality creterias,the options used in quality index are smooth,place node,element optimize,drag trias which is helps reduce trias.also combine trias.
finally checked quality parameters successfully and saved model.
RESULT
Finally midsurfacing,geometry cleanup,automesh,quality parameters are done successfully.
