Week 2 Challenge : Surface meshing on a Pressure valve
Aim:
To mesh the given model by checking the geometrical errors and perform Topology cleanup accordingly also to set three different target lengths as three different cases and mesh the model.
- Target length = 1mm, 3 mm and 5 mm
- Element type = Tria
Procedure:
First select topo and shaded mode intially from the deck


Given geomentry model check and do topo clean up intially from face deck then change resolution in settings to 1mm perimeter length move for further step.

cleanup geometry by filling the surface and holes in the geometry, clear all the single coons.
use the cons>fill hole option or face>New option.


After finish cleaning the geometry check them using check from top deck

Then assign the Pid so that it will be easy to select them for further use by pid manager
properties window will pop up




After assigning check the intersection error if there then clear them out by going to the Face>intersect then select which are the two components you need to work on in this first select the column then go for spring as second after selecting the do the middle click it assign them.

Then deleting the unwanted on and by keeping the important ones clear this error then go for check manager and check them.

Then finally bring all the components together then go for mesh deck.

assign the given length one by one in perimeter also give min and max limit in mesh parameter and in quality criteria too.

In mesh parameter give the element type as tria.


after finish giving the datas go to deck mesh generation>CFD then give the mesh as visible.

Do this process for all three cases.
Observation:
case 1: 5mm target length


case 2: 3mm target length


case 3: 1mm target length


Conclusion :
As you can observe the greater the target length the shape of the component while meshing is less precises from outlook it may seem ok but for tiny components which has compact surface it won't be precises.
Then the lesser the target length value given the shape of the component will be more precise while meshing it won't affect the components which has compact surface.
In the given cases as you can see the 1mm mesh has good shape for the spring instead of 3mm and 5mm the precision of the geometry shape depends on the mesh target length.
