DEFINITION
DIEGEO specifies the boundary geometry of an object.
REMARKS
DIEGEO boundary geometry may be used to specify a geometric profile of a rigid object or to define the object geometry for automatic mesh generation. DIEGEO information can be described by points or entities (lines and arcs). The remarks presented in this section refer to the point description geometry type. Radius(i) is the radius which will be placed at the intersection of the lines formed by the Point(i) and Point(i-1) and Point(i) and Point(i+1). The profile geometry must be continuous, but does not need to represent a closed curve. If the geometry is a closed curve, the data should be ordered counterclockwise. If the geometry is not a closed curve, the geometry should be ordered counterclockwise such that the rigid object interior lies to the left of the profile geometry as would be the case if the entire closed shape had been drawn. Lines of symmetry should lie on either the global X or Y axis. If the geometry represents a closed curved, then X(1) = X(Ndata), Y(1) = Y(Ndata), and Radius(1) = 0 and Radius(Ndata) must be a non-zero value. If the geometry does not represent a closed curve, then Radius(1) = Radius(Ndata) = 0. If a point other than an end point contains a zero radius, it will be treated as a straight line segment connecting the previously defined point. Applicable object types: Rigid, Elastic, Plastic, Elastoplastic, Porous
WARNINGS
If Line/Arc is read from Keyword File the geometry must be checked each time.

DEFINITION
DIEGEO specifies the geometric data of a rigid object.
REMARKS
DIEGEO information can be described by points (Gtype = 1) or entities (lines and arcs, Gtype = 2). The remarks presented in this section refer to the entity description geometry type. Entities can contain geometric information for lines or arcs. XStart(i) and Ystart(i) refer to the coordinates of either the starting point of a line or the starting point of an arc. XEnd(i) and YEnd(i) refer to the coordinates of either the ending point of a line or the center point of an arc. The profile geometry must be continuous, but does not need to represent a closed curve. If the geometry is a closed curve, the data should be ordered counterclockwise. If the geometry is not a closed curve, the geometry should be ordered counterclockwise such that the rigid object interior lies to the left of the profile geometry as would be the case if the entire closed shape had been drawn. Lines of symmetry should lie on either the global X or Y axis. Applicable object types: Rigid
