Layout3D

Type:section Appearance:simple

A Layout3D section for a 3D geometry looks like this:

Layout3D {
  UnitOfLength = 1e-9
  BoundaryConditions {
    Boundary {
      Direction = Horizontal
      Class = Transparent # Periodic
    }
    Boundary {
      Direction = Vertical
      Class = Transparent
    }
  }
  Extrusion {
    Objects {
      # 2D definitions (x-y-coordinates)
      Polygon {
         Name = "ComputationalDomain"
         DomainId = 1
         Priority = -1
         Points = [0 0, 500 0, 500 500, 0 500]
      }
      Polygon {
        Name = "Triangular Object"
        DomainId = 2
        Priority = 1
        Points = [100 100, 400 100, 100 400]
      }
    }
    # extrusion to 3D (z-direction)
    MultiLayer {
      LayerInterface {
        BoundaryClass = Transparent
        ExteriorDomainId= 10
      }
      Layer {
        Thickness = 40
        DomainIdMapping = [1 11, 2 12]
      }
      Layer {
        Thickness = 20
        DomainIdMapping = [1 11, 2 13]
      }
      LayerInterface {
        BoundaryClass = Transparent
        ExteriorDomainId= 11
      }
    }
  }
}

The 3D layout consists of a 2D part (where different shapes are defined in an x-y-coordinate system) and a Extrusion section which defines how the 2D shapes are extruded in the third dimension (z-coordinate). In the different layers of the extrusion, different domain identifiers can be attributed to the extruded shapes. Also extrusions with non-rectangular side-walls are possible which allows for the creation of, e.g., corner roundings in z-direction, spherical shapes, etc.

Please also consult the geometry tutorial which comes with the software distribution for a detailed description of the layout format.
