Next some help geometries are created that will be subtracted from the initial Design Space. For these steps the Design Space is hidden.
At first we need to define regions where accessibility is needed
Therefore, the split tool with the offset function as split method and a value of 3 mm is used.
Ensure to use “partition” as split behavior
...
After this the Access Regions based on the cells can be created.
Therefore, the Access Region Tool in the Optimisation Tools is activated.
A sufficient extrude Distance is entered and the face of the created cells is chosen to create the according Access Region.
It’s recommended to choose a scaling factor for the Access Regions to have a little bit extra space for the assembly work later on (see 1.1).
...
Create the material in the Materials editor and assign it to the Design Spaceand Retained Volume. It is possible to create a separate material for the Retained Volume. In this case the material behaviour is Isotropic.
The specific values needed are the Young's Modulus (72000 MPa), Poisson ratio (0.34) and Density (2.7e-6 kg/mm3).
The Tension Strength is the maximum allowable stress for the material and is set to 460 MPa.
...
Inside the Post Processing the von Mises stress and the displacements are visible for all iterations and for every Event. The Scale can be influenced individually
