	Mechanical validation tests class Our validation tests are based on the following Thesis: "Development of Membrane, Plate and Flat Shell Elements in Java" Kaushalkumar Kansara, May 2004 In this thesis, the same formulation has been chosen to simulate the plate bending deformation, based on Batoz et al.

	Wraps glewInit() to separate the glew opengl definitions from the osg opengl definitions only imgui needs glew but we need to call glewInit() from a osg callback, using this call we avoid getting warnings about redefinitions.

Function Documentation

membranePlateWithSemiCircularHoleAddNodesForAngle()

void SurgSim::Physics::membranePlateWithSemiCircularHoleAddNodesForAngle	(	double	angle,
		size_t	numNodes,
		double	L,
		double	radius,
		std::vector< Vector3d > *	nodes
	)

Helper function to define the nodes of the membrane plate with semi-circular hole test In this test, nodes are defined around concentric circles.

This function adds the nodes that are along the same axis (going from the most interior circle to the most exterior circle) for a given angle.

Parameters

	angle	The angle for which the nodes will be computed and added
	numNodes	The number of nodes to add along this axis (defined by the angle)
	L	The length of the plate
	radius	The radius of the most internal circle
[in,out]	nodes	The list of nodes in which the new nodes will be added

Note

The spacing between 2 consecutive nodes is constant equal to (L / 2.0 - radius) / 5.0
