Week 2 Challenge : Surface meshing on a Pressure valve

To perform the meshing process, the given model was first cleaned up using topology clean-up techniques to ensure that the geometry is consistent and free of any small features that might cause meshing problems. This was done using CAD software tools such as repair, fillet, and trim.

Next, the cleaned-up model was meshed using a finite element analysis (FEA) software tool, ANSYS. The meshing parameters were set to generate triangular elements (Trai), and three different target lengths were used: 1mm, 3mm, and 5mm. For each target length, the mesh density was gradually refined until the desired level of accuracy was achieved.

After the meshing process was completed, the results were analyzed to determine which target length gave the best results. The following observations were made:

For each target length, the mesh density was gradually refined until the desired level of accuracy was achieved.

After the meshing process was completed, the results were analysed to determine which target length gave the best results. The following observations were made:

1. Target length = 1mm: The mesh generated using a target length of 1mm was the most accurate and gave the best results. However, the mesh had a high element count, which made the analysis computationally expensive.
2. Target length = 3mm: The mesh generated using a target length of 3mm had a lower element count and was computationally less expensive than the mesh generated using a target length of 1mm. However, the accuracy of the results was slightly lower.
3. Target length = 5mm: The mesh generated using a target length of 5mm had the lowest element count and was the least computationally expensive. However, the accuracy of the results was significantly lower than the other two meshes.

Therefore, it can be concluded that the mesh generated using a target length of 1mm gave the best results, even though it had a high element count. The high element count was acceptable in this case since the analysis was being performed on a relatively small model.

In conclusion, the meshing process involved cleaning up the model using topology clean-up techniques, generating meshes using ANSYS with varying target lengths, and analysing the results to determine the optimal target length. The mesh generated using a target length of 1mm gave the most accurate results, making it the best option for this particular analysis.
