Week 2 Challenge : Surface meshing on a Pressure valve

AIM:

       To mesh a pressure valve using three different mesh sizes and find out the optimal mesh size.

OBJECTIVES:

         Check for the geometrical errors and set the three different target lengths and mesh the model by given target lengths 1mm,3mm and 5mm.

PROCEDURE:

1.Geometric error corrections have been done with the help of the phases tool in the topo and we can alsomuse fill hole options in the cons.

2.After once completing assign property id to different components of the pressure valve for which the tools used are NOT,i not,OR etc.

3.After completing geometric and intersection corrections we have to mesh the given components in three different target lengths.

CASE-1-Creating 1mm mesh:

We need to click on the mesh parameters tool, in which click to cfd method.once then check if the element type is in tria as asked and then provide the minimum and maximum total length as 0.5 and 1.9, coz we will be getting the values of total length near to 1mm. since we cannot get the perfect total length but an approximate one.Once then get to the classic mesh tool and click auto cfd in spacing in perimeters.Then click on the mesh generation and the cfd and visible and get the final result of tria mesh of total length approximately to 1 mm.

 CASE-2-Creating 3mm mesh:

We need to click on the mesh parameters tool, in which click to cfd method.once then check if the element type is in tria as asked and then provide the minimum and maximum total length as 2.5 and 3.3, coz we will be getting the values of total length near to 3mm. since we cannot get the perfect total length but an approximate one.Once then get to the classic mesh tool and click auto cfd in spacing in perimeters.Then click on the mesh generation and the cfd and visible and get the final result of tria mesh of total length approximately to 3mm.

 CASE-2-Creating 5mm mesh:

We need to click on the mesh parameters tool, in which click to cfd method.once then check if the element type is in tria as asked and then provide the minimum and maximum total length as 4.6 and 5.6, coz we will be getting the values of total length near to 5mm. since we cannot get the perfect total length but an approximate one.Once then get to the classic mesh tool and click auto cfd in spacing in perimeters.Then click on the mesh generation and the cfd and visible and get the final result of tria mesh of total length approximately to 5mm.

RESULT: 

 The meshing of 1mm,3mm and 5mm has been done and the results have been found.

CONCLUSION:

 From the above, hence we can find the  case-1-1mm is much better and has the better approximate result and the spring surface than the case -2-3mm and case-3-5mm.
