This tutorial describes how (mesh) modifications can be passed to ACP and also highlights a few advanced features of ACP:
A: Modify Mesh and lay-up
B: Work with Edge Set and a Tube Rule to define local reinforcements
C: Taper a Core
D: Cut-Off Rule in combination with a Core
E: Create a Solid Model for further purposes.

A: Modify mesh and lay-up
• At the end of the Tutorial 1, the critical failure mode was matrix failure in one layer of the top face sheet which consists of three UD plies with equal orientation.
• The goal is to optimize the layup to increase the strength of the composite structure. First, the 3 UD plies will be replaced and a refined mesh will provide more accurate results.
• To start, open the archive “tutorial_2.wbpz” and open Mechanical.

A: Modify mesh and lay-up
• For the next part of the exercise, define a Named Selection with the 2 edges starting at node (-150,-150,0). Name it “taper_2_edges”.
• Insert a Face Sizing of 10mm for the plate.

A: Modify mesh and lay-up
• Update your model.
• Don’t forget to verify the status of the different steps of the analysis. If the Model is not up-to-date, ACP (Pre) Setup will have the Status “Input Changes Pending”.

Proprietary
A: Modify mesh and lay-up
• Edit the ACP (Pre) Model, and modify the modeling ply “Upper_ply” to obtain the same ply as for the bottom part (Material, angle and number of layers)

B: Create Edge Set and a Tube Rule for a new ply
• Create an Edge Set derived from an Element Set:
• New Edge Set
Negative limit angle value
-1: No limit angle
Origin defines the starting
point to find the edge.

• Create a Tube Rule:

C: Taper Edge for Core
• Modify the core:
• Thickness distribution of this ply:

Proprietary
D: Cut off Rule for Core
• Import CAD Geometry “Core_limit.stp”:
– Add a single component Geometry in the project schematic
– Import the geometry file “Core_limit.stp”
– Create the link between Geometry and ACP(Pre) Setup.
• Refresh ACP(Pre) Setup:
The CAD Geometry is automatically imported
and scaled in the case of different unit systems.

D: Cut off Rule for Core
• Define a new Cut-off Rule:
• Hide / show CAD Geometry

D: Cut off Rule for Core
• Modify the core:
• Updated core thickness distribution

Proprietary
E: Create a Solid Model
• Create a new Solid Model:
• Updated thickness contour plot of the Solid Model

Proprietary
E: Create a Solid Model
• Deactivate the Solid Model and solve the model again
• Modify the lay-up definition as you want and observe the differences.
• Modify also the Cut-Off Rule definition. For example, if you deactivate the option Ply tapering the core thickness distribution is quite different.
