Week 2 Challenge : Surface meshing on a Pressure valve

Aim: To perform Surface meshing on a Pressure valve using ANSA for target lengths of 1mm, 3mm and 5mm.

Procedure:

Step 1- Open the model in topo mode in ANSA. Perform a geometry check,if there are any errors, it can be noticed with the red lines.

Step 2- Use surface algorithms to to remove the holes from the surface and geometry check one more time(triple cons are ignored).

.

Step 3-Assign PID for each component using the tools PID,ENT,PID region(property ID &entity).

Step 4-Change to surface mesh mode and assign the value of perimeter and macros to 1 mm, change the values of mesh parameters and attributes.

Step 5- Repeat the same step for mesh length of 3mm and 5mm.

Result: Thus surface meshing of a valve was performed using ANSA for three different target lengths.

Conclusion: Target length Total triangle meshes

1mm 210015

3mm 23959

5mm 8782

Smaller the target length better is the accuracy of the mesh(More meshes=More accuracy). As the target length decreases the original shape of the entity is maintained.
