Week 2 Challenge : Surface meshing on a Pressure valve

AIM: To set the target length for the given model and mesh the model using ANSA.

ONJECTIVE: Check the geometrical errors in the given model and perform the topology cleanup accordingly. Set the three different target lengths as three different cases and mesh the model.

• Target length = 1mm, 3mm and 5mm
• Element type = Tria

PROCEDURE:

• First of all we insert the given model in the ANSA.
• Then we check the unit in mm.
• Then we check the resolution of the given model
• Then we check the geometrical errors. If the geometrical errors is there then the all resolve the all geometrical erros like single coons, triple coons, intersection errors etc.

• My geometrical errors is resolved.
• Then we go for mesh the given model
• First of all we set the target length = 1mm, 3mm and 5mm.
• And Element Type = Tria
• We use CFD Meshing in the whole model of the needed target length.
• First we set the Target length = 1mm and meshed the given model.

Whole model is meshed under 1mm target length

• Now we set the Target length = 3mm and meshed the model

Whole model meshed under 3mm target length

• Now we set the Target length = 5mm and meshed the model.

Whole body meshed under 5mm target length

CONCLUSION:

• So I conclued that how to rectify the geometrical error of the model
• when we set the 1mm target length we found that refine meshed is there and 3mm and 5mm target length meshed is not so good.
• When we set the target length 1mm of the model, total number of element is 133549.
• When we set the target length 3mm of the model, total number of element is 22691.
• When we set the target length 5mm of the model, total number of element is 9228.
