Week 2 Challenge : Surface meshing on a Pressure valve

Aim:

Now in this week i've complete to check the model like Geomentrical check and patch the surface and Topo Cleanup the model and mesh the model.

Procedure:

• First we need to check the model so select geometry check and select all the options, put tic mark and then click execute if any error occur in that tab select the error in the model.
• There is a surface in open condition we are expecting the surface in close condition. so, we have to close these geometry single cons. so, then only we able to do volumetric mesh and CFD Analysis.
• so those single cons error called as topo cleanup.
• In topo cleanup there is a FACE option in that there is a NEW Option. This NEW Option is used to create a new surface as the name suggest. in that new there are different whichis used to creat a new surface which is used for filling hole a which is present in existing surface.
• If we select that option and we should select all the single columns in order to ensure that we want this particular surface.
• In Topo clean up there is fews are available there are, STEP-1 checking the geometry and solving the geometry only that if confime the gemoentry is well enough then now you can start the meshing process.
• STEP-2 the task is be to much the surface or close the surface. so, for the situation we will deal with only"face and surface" section only to path this surface problem.
• STEP-3 : TOPO->Face->NEW->(i)Existing Surface ->select the single cons -> and middle click -> surface created. that is use existing surface if any hole in that surface.
• STEP-3 (ii).COONS -> select the cons(loops)-> middle click->if its ok click ok or click alter that is used to select a single shot surface hole.
• Fitted -> click loops -> select the cons -> preview is showing if its ok click ok or click alter and middle click. that is this option is same as coons.
• ANOTHER WAY TO PATCH THE HOLE cons-> fill hole -> select the hole present in the surface -> middle click -> surface is created. (i.e) this is also are of the way to created the hole only (circular, rectangle, square) shap allowed.
• Face -> NEW -> fitted -> ent select the line ->middle click ->surface created (i.e) the ENT option is used to select the single line after select click middle click.
• To turn off the DOUBLE cons & TRIPLE Cons and cross option. we can see the hole if its thee this is the way to cross check the surface.
• TO enable the wire frame mode click CONTROL + SHIFT OT GETHER = WIRE FRAME MODE.
• STEP-4 After patching the surface hole is completed the check the geometry once again and click execute to verify al surface. if the status is ok then it is ready for the volumetric meshing. so, this is the way a how we can do the clean up.
• And to remove a small surface click CUT-> right on the small surface ->that line is changed color into orange ->and it is disappear.
• To create a new PID click properties ->right click -> NEW -> PSHELL -> NAME (OUTLET).
• Select the anyone PID an right click apply in the properties and select cross edge in the model and middle click.
• Enable "NOT" Option and click PID and click any selected region the entire region will be got disappear.
• To assign the PID for the particular component in a model. Click PROPERTIES -> in that Right Click -> NEW -> PSHELL ->NEW POPUP(NAME)-> Enter the component name -> ok.
• To Enable that component like assigning PID click the components like properties ->and Right click apply ->in the component name in the properties ->and right click apply-> in the middle enable "ENT" mode-> select the component in the middle -> middle click -> the PID is assigned for that component.
• The "LOCK" option is used to lock current state edited model. And we work edit in tha model after we click the "ALL" button it will bring the middle to initial locked stated.
• The "NOT" option is used to hide the particular part with out hideing a neighbor.
• TOPO -> Click Undeleted option -> in that middle they shoowo the deleted line and some joint , parts are deleted by me (line will be in white colour).
• now to meshing for the entire model click mesh -> length -> select perimeter (enter (1))->select macro(enter (1))-> mesh parameters(1)-> quality criteria (min(0.5))&(max(2)) spot mesh -> mesh parameter (element type (TRIA))-> select the model and middle click the mesh is applied.
• measure tool is used to the length and diameter.
• Before creating a mesh make sure that the length, mesh parameter, quality criteria i applied correctly.
• To REmesh the component click the TOPO->Select "OR" option ->PID -> click the respective surface ->click quality criteria (min(0.5)) & (max(2))-> mesh parameter (target length(1)) & (min(0.5)) & (max(2))->in mesh click length parameter (1), macro(1) -> spote mesh (visible).
• "OR" option is used select only selected component and the neighbour element are gets hidden.
• "ERASE"option is used to used to earse the mesh applied in the modle.
