This block holds definition of input geometry (surfaces).

• Each surface can be used to:
  • specify refinement for any mesh cell which:
    • intersects the surface
    • lies inside of a (closed) surface
    • lies outside of a (closed) surface
    • lies near a surface
  • define the boundary and snap the mesh to the surface.

   

• Besides the input surface, user can directly define following objects:
  • searchableBox

        myBox
        {
            type searchableBox;
            min (-1.0 -0.7 0.0);
            max ( 8.0  0.7 2.5);
        }
    

  • searchableCylinder

        myCylinder
        {
            type searchableCylinder;
            point1  (1 0 0);
            point2  (2 0 0);
            radius  0.1;
    

        myDisk
        {
            type searchableDisk;
            origin  (0 0.5 0);
            normal  (1 0 0);
            radius  0.01;
        }
    

  • searchablePlane

        myPlane1
        {
            type searchablePlane;
            planeType pointAndNormal;
            pointAndNormalDict    
            {
                basePoint    (0 0 0);    
                normalVector (1 0 0);
            } 
        }
    

        myPlane2    
        {
            type searchablePlane;
            planeType embeddedPoints;
            embeddedPointsDict    
            {
                point1    (0 0 0);    
                point2    (1 0 0);
                point3    (0 1 0);
            } 
        }
    

  • searchablePlate

        myPlate
        {
            type searchablePlate;
            origin (0 0 0);
            span (1 1 0); 
        }
    

  • searchableSphere

        mySphere    
        {
            type searchableSphere;
            centre (0 0 0);
            radius 0.1;
        }
    

   

• Each input geometry is defined as a block starting with the name of the file (inside the triSurface directory) and including:
  • type triSurfaceMesh; – always the same for all input files
  • name patchName; – user defined name to be used for referring to the input geometry

   

• The geometry block can contain any number of geometry parts or implicit objects:

   

  geometry
  {
      C-fine.stl
      {
          type triSurfaceMesh;
          name C;
      }
      F-fine.stl
      {
          type triSurfaceMesh;
          name F;
      }
      D-fine.stl
      {
          type triSurfaceMesh;    
          name D;
      }
      
      disk
      {
          type searchableDisk;
          origin  (0.6925 0.5 0);
          normal  (7 -2 0);
          radius  0.1;
      }
  }
