Surface Mesh the model using ANSA software with the tools taught in the Lecture

Challenge 1

Name: Mesh the model using the tools taught in the Lecture.

# Use element size as 1 unit

Objective:

• To perform geometry check
• To set property ID for parts in model
• To set mesh length as 1mm
• To generate surface mesh for given parts

Methodology:

• First of all,i opened ANSA from command window of Computer.
• Then imported CAD file from folder with suitable file extension converter selection for ANSA.
• Then following below steps,I set quality criterion to make every detail visible to operator.

Quality Criteria- presentation parameter- Draw cons in PID mode as in ENT mode-ticked-set lower slider to all details-apply-OK

• Then performed geometry check for given model for checking topological error in parts by following below path

Check- geometry-Ticked all criteria to be checked-execute

• Once we have confirmation of topological error free geometry,now we can go to set PID to parts in CAD model

TOPO module-Faces-SET PID-Select Part or entity in three group-new-named them –ok

We can check PID by clicking on P on top as shown in following screenshot

• Then set mesh length for meshing by following below steps

Mesh module on top right corner-perimeters-lengths-perimeter-select all entity to by selecting require part by pressing left key of mouse then confirm selection my middle click of mouse-set length to 1mm-OK

• Then created surface mesh by following below steps

Mesh module-mesh generation- spot mesh-select entire geometry or required-clicked middle mouse button –mesh generated

• Save this file at required destination.

Results:

• Now we have created surface mesh for given assembly and we have to check whether all macros are meshed or not and is there any issue with mesh by performing following check? And it can be observed that surface mesh is good and error free.
• Checks-check manager-surface mesh check-execute-ok
• 
• Then we have to check mesh length by measure-node-select two adjacent nodes on mesh by left click of mouse-then observe whether it is conforming to requirement or not and its good.
• 
• 

Learning Outcome:

• Learned about ANSA interface
• Learned about how to check topological error
• Learned about how to set PID.
• Learned about how to set mesh length.
• Learned about how to generate mesh.
• Learned about how to check surface mesh for quality.
• Learned about how to measure mesh length.

Conclusion: This assignment gave us brief introduction to steps need to be followed to create surface mesh for given CAD file right from importing to mesh generation.
