Week 2 Challenge : Surface meshing on a Pressure valve

Aim:

To mesh the given model by using spot mesh and the target mesh length is 5mm,3mm & 1mm the element type is tria.

Procedure:

1. first import the model by using file>open>select the model.

2. Before doing mesh need to define the model without any error by using tools>check>geometry option.

3.Converting single cons into double cons by using faces>new option for adding new surfaces.

4. And then assign the PDI for the given model by using properties>new>pshell>assign the name and then apply the PDI for the given model.

5. After that we have to make the cut by using macros>cut for removing the smallest area of the given model.

6. and then click the mesh>perimeter>length option and giving the target length as per the given.need to give the target length in perimeter as well as macros ( 5mm,3mm & 1mm).

7. And then go to quality criteria select the mesh parameters and given the target length as well as select the element type(tria) and mention the minimum and maximum target length.

Case 1 Target length = 5mm

1) To mesh select the meshing modul

e, select the Length under Perimeters and give 5 mm as Perimeter and in Macros.

2) In the meshing parameter give Maximum target length as 7 mm and Minimum target length as 3 mm, for mesh type select Tria.

3) In the quality criteria give Maximum target length as 7 mm and Minimum target length as 3 mm.

Case 2 Target length = 3 mm

1) To mesh select the meshing module, select the Length under Perimeters and give 3 mm as Perimeter and in Macros.

2) In the meshing parameter give Maximum target length as 5 mm and Minimum target length as 2 mm, for mesh type select Tria.

3) In the quality criteria give Maximum target length as 5 mm and Minimum target length as 2 mm.

Case 3 Target length = 1 mm

1) To mesh select the meshing module, select the Length under Perimeters and give 1 mm as Perimeter and in Macros.

2) In the meshing parameter give Maximum target length as 2 mm and Minimum target length as 0.5 mm, for mesh type select Tria.

3) In the quality criteria give Maximum target length as 2 mm and Minimum target length as 0.5 mm.

Conclusion:

For considering the 3 cases case 3 will be giving the more accurate resutls during computation. because less target length giving more elements of the model.and one more thing more number of elements taking more time during coputation apart from that it will be giving more accurate results.
