Hyperworks basic
Aim
To understand basics of Hyperworks and meshing
To use the meshing and Geometry cleanup tools
To implement the learnt tools while working on models
Objective
1. Using the given 2D Drawing create a simple bracket in HyperWorks.
2. Element size: Min.Length=2mm, Target length=5mm, Max.Length=8mm
3. From the given FE model extract the CAD surface.
1. Given 2D Drawing
Creating 4 nodes in the co-ordinate system
Go to Nodes select 
give co-ordinate values and create
Step 1
Step 2
Step 3
Step 4
Go to Lines select 
join the nodes by selecting Linear Nodes
Go to Tools -> Translate
Select nodes to be translated and give magnitude value
Click on nodes and duplicate them and with respect to axis click translate +/-
Press F4 and check distance between nodes
Join the nodes using linear nodes
after joining
Create fillet of 5mm
Clear nodes - Go to Temp nodes > select the nodes and clear
After creating fillet delete the line in mid
Surface Creation
Go to Surfaces -> select ruled 
Pick one end and click on mouse middle button and pick other end and click on mouse middle button -> Surface will be created
Create a fillet of 15mm on lower side
Create Surface
Create nodes and a mid node using 
Interpolate nodes
Translate the mid node to 30mm below where hole need to be created
Create Circle using
circle with radius in Line option
radius = 5mm with screen normal
Go to Surface edit -> Trim with lines and normal to surface
Delete the trimmed surface
Hole is created with 5mm radius
Create two nodes in the base
Translate and rotate to 60mm
Create two nodes with 30mm distance
Join nodes diagonally with above nodes
Trim the lines with respect to surface and delete
after deleting unwanted lines join the lines
Create nodes on base center to create rib
Go to ribs -> select N1 - base node N2 - N1 above node N3 is last node
Starting node and end node to be selected
Delete unwanted lines and surfaces
Geometry cleanup was done
Rib dimension = 40mm diffference due to fillet
Base dimension = 100mm
2. 2D Meshing
Element size: Min.Length=2mm, Target length=5mm, Max.Length=8mm
Given Stp model
Geometry Cleanup
Washer slip of 5mm was created around the circle in mid
Meshing was done step bt step
Minimum Length was found within limit
Maximum Length was found within limit
3.Extracting CAD surface from given FE model
Given Meshed FE (Side body) model
Go to Surfaces 
from FE option
In Elements -> Select all elements and select create
FE to CAD Surface
After extracting from FE some surfaces were not found
Surfaces were filled using 
ruled tool in Surfaces
FE to CAD extracted surface (Side door)
Conclusion
1. Learnt to create CAD Surface of bracket using Hyperworks
2. Learnt to use meshing tools and performed 2D mesh on given model
3. Extracted Cad Surface from given FE model
