As a first step, We import the model & then visualize it. So, as can be seen in the image (in topo view) there are some free edges at the boundaries & at center. But we are not correcting them because as the complexity of the model is high, it will not become a hurdle while creating a mid-surface via manual method.
- MID-SURFACE GENERATION & TOPO CLEANUP:
After this we need to generate a mid-surface, so for that we have to choose a suitable method to generate mid-surface. So, as per the measurement the base has 2.8 unit, at boundary 2 unit and where ribs are 2, 5, 10, 27 & some dog-houses are there. So, in conclusion it looks like a plastic component. It is a very complex model where the auto-mid surface generation will not work.
So, In manual method first we create a mid-surface of 'base surface' then we create a its ribs & dog-houses. And using some commands like, extend, trim we will attach it to the base surface. We can see the generated mid-surface in the image below. Also some cons are suppressed to avoid element failures.
- MESH GENERATION:
After geometry cleanup, it's time to generate the mesh. Before creating a mesh don't forget to set the quality criteria in the model as per given. For this model, I am not sure from which portion I have to start the mesh. So, I meshed all surfaces in one hit and then cleared the failed elements one by one.
Criteria file.
- ASSIGNING A THICKNESS:
Here to assign a thickness an auto option (Mesh > assign > Midmesh thickness) is used to create midmesh thickness.
4. CONCLUSION:
The Challenge is completed for the plastic model And As per me this part has a difficult feature where I have completely lied on manual methods. So overall it's a good practice for the use of manual tools.
Problems faced.
Facing crash of Hypermesh interface when the trias are reduced or nodes are replaced in the open gaps and faces.
