Project 1 - 2D meshing on the instrumental Panel

Aim: To Prepare the Given Model for Pre-Proprocessing ANSA v20.14

Preprocessing Procedure Includes:

1.Increase Cons Resolution to 5

Before

After

2.Apply TOPO

3.Measure Different Areas of Given Model

4.Geometry Check & Solve Errors if Found

--After Geometry Check

--After Errors Solved

---I use ANSA fix Option to Solve Errors Automatically by ANSA & i use manual options to solve errors which are unable to fix by ANSA

5.Generate MID Surface

--I use manual option to generate Mid Surface for Uniform Thickness Area

--For Varying thickness Area or Dog or Cylindrical Type Elements I Create Mid Curve using TOPO->Curves->Middle Tool & create new surface using Topo->Faces->New->Coons Tool option & Assingned New PID for that Element with respect to its Thickness

--After Middle Curves Using CAD

--After Creating a Middle Face Using Curves & Assigning NEW PID using TOPO->Faces->Set PID Tool

--After Full Middle Surface

6.Apply Mesh and Quality Parameters Before Starting Mesh

Quality Parameters:

Mesh Parameters:

7.Defeature the Mid Surface areas Before Performing Mesh

--I use to Defeature Some areas like Curve regions, Dog or Fin Like Regions to get better Results after Mesh.

Like Mentioned Below

Before Defeaturing and Mesh

After Defeaturing and Mesh

8.Meshing

--I used to perform Meshing Manually to get Better Results and to Overcome Elemental Failure but at some places i got Some OFF Elements which i am unable to Eliminate. When i am trying to eliminate this OFF's my Feature Capturing of Mid Surface is Getting Affected So, i use to keep it as it is.

After Meshing of Different Regions

9.Save .ansa File After Meshing

Learning OutComes:

-Learned How to Prepare Varying Thickness Complicated Model for Preprocessing.

-As It is Very Complicated Project so i use Manual Mid Surfacing and Manual Meshing to Get Better Results as Auto Mid & Auto Meshing Doesnt Capture Features Properly and there is lot of Work Required after Auto Mid& Meshing.

Conclusion:

After Completion of This Challange I can Perform Meshing to any Varying Thickness Complicated Model.

I have Taken Nearly 8Hours to Generate Mid Surface Manually and Total 17Hours to Complete This Challenge with Given Quality Criteria.
