Detection of Mechanical Deformation on Surfaces
According to mechanical theory, when a solid body's atoms move in response to an applied force, their movement creates local strain, which causes the body to change in size and shape. This implies that the body gets distorted in some way.

Detection of Mechanical Deformation on Surfaces
Deformations can happen on surfaces due to issues while importing the files to hyper-mesh or issues caused during the model's design.
What is the Mechanical Deformation Theory?
According to mechanical theory, when a solid body's atoms move in response to an applied force, their movement creates local strain, which causes the body to change in size and shape. This implies that the body gets distorted in some way.
How to Fix Mechanical Deformation on Surfaces?
We need to visualize the model manually and clean up the geometry using geometry clean-up tools. The steps include:
- See the deformation in the surface shown below.
- Goto Geometry > Quick edit > Release point
- Release these points
- Post-release, you will find the area as shown below.
- Now, we need to join the surfaces together using the “toggle edge” tool.
- Goto Geometry > Quick edit > Toggle edge
- Use the “toggle edge” tool to toggle between the free edges present.
- You can find the area as shown below after joining them.
- Now we can use the Geometry > Quick edit > Replace point tools to rearrange the construction lines.
- Now replace the points and suppress the lines that are shown below
To suppress the line use: Geometry > Quick edit > Toggle (Ref Fig:5)
- Finally, you will find the region as shown below.
Finding and Fixing Unnecessary Mechanical Deformations like Pinholes
Pinholes and beads that have a very small size (i.e., which have a size less than the target element size) can be removed from the geometry.
Take a look at the pinholes shown below
These features can be deleted, and we can patch the surface as shown below.
