Week 2 Challenge : Surface meshing on a Pressure valve

AIM:

The main objective of the challange is meshing the pressure valve in different target length and find the best mesh length.

PROCEDURE:

Open the model in the ansa software,and perform the checks the geometry on the model.

By the help of that check remove all the single cons,and mixed cons too.

then start the topo cleanup by the helping of the fillhole and new faces (plannar).

these cleanup are done with the help of wire frame mode for seeing the correct length of the single con selection.

in topo mode there is no single and triple cons is present.after doing all the topo cleanup and all geometry corrections.again the model have to check by using the checks -geometry-exectue.

now the pid is created for the all the parts of the pressure value,by giving the name to the parts like(body,inlet,outlet,spring,dome,rod,column.)

now go the mesh deck and do the first case of target length 5mm by the help of the quality criteria by giving the target length as 5mm.

then mesh -perimeter-length-permieter-select pid region and put the length as 5mm.

then marocs and select the all pid region and put 5mm as a target length.

finally, mesh with the spot mesh .

now the second case should be started.by changing the quality criteria as 3mm and repeat the same procedure for perimeter and macros .just change the length as 3mm.

now go to the mesh with best mesh and then make it visible.

now the last case the mesh was done with 1 mm by changing the mesh target length as 1mm.

repeat the same procedure again for this mesh too,as like past 2 .

mesh with the best mesh with visible.

RESULTS OR OUTCOMES:

Among the three cases the third one is the best meshing for this pressure valve(1mm).because the number of mesh is high so the analysis is so deeper and also there is no change in shape.every parts of the pressure valve is same as original one.the spring and dome are in the same as the original shape witha proper geometry and get the good surface finish too.hence among the three casdes of the meshing the pressure valve the 1mm meshing is accurate for this process.
