This example tests the geometry fitting capabilities of CMISS. A half sphere initial mesh is defined using 2D cubic Hermite and Hermite simplex elements. The initial mesh has a radius of 1.8. 400 data points have been generated (via a 'c' program) about the half sphere. The data is generated according to the following scheme:
Boundary conditions on the problem are that nodes on the edge of the half sphere retain derivatives normal to the plane intersecting the sphere. The theoretical solution to this problem is a half sphere with radius 2.0. Due to the randomness of the data distribution, this will not be obtained, but the error is reduced to 0.03.
If it is necessary to view the results, run the CMISS comfile geom_sol and then the CMGUI comfile geom_draw.
