Parameter definition
Description
This command is used to subdivide a structure into multiple layers. The original mesh can be curved, but must have only one element in its thickness direction. Further, the command can only operate on meshes consisting of linear hexahedra and linear pentahedra elements.
The layers are defined in a TABLE, going from front face (first row) to back face (last row). The plate orientation is defined through $(x_f, y_f, z_f)$. This coordinate should point on the front face.
Each row in the TABLE has 5 columns, listing (1) layer ID (arbitrary number), (2) part ID, (3) layer thickness, (4) number of elements in thickness direction and (5) a merge flag. By default, the different layers do not share nodes. By activating the merge flag at a layer $i$, this layer will be merged with layer $i+1$.
The relative thickness of a layer is the fraction of the original component thickness. (The reason for working with relative and not absolute layer thicknesses as default is to manage handling structures with local thickness variations.)
Absolute thicknesses (absolute=1) are typically used when modeling structures with two face layers and a core, where the face layers have fixed thicknesses. Absolute thicknesses are then specified for the face layers and 0 for the core. 0 means that the core layer thickness is defined as the original part thickness minus face sheet thicknesses.
Example
Subdivide a part into multiple layers
Example of how a solid component can be replaced by a layered structure.
Absolute face sheet thicknesses
Example of a sandwich structure where the face sheets have a fixed thickness and the core a varying thickness.
