EX_PLANESTRESS3 NAFEMS benchmark model for stress of a tapered membrane.

[ FEA, OUT ] = EX_PLANESTRESS3( VARARGIN ) NAFEMS benchmark for stress of a tapered membrane. Two test cases are modeled, the first with the x displacements fixes on the left boundary while a horizontal force is applied to the right boundary. Secondly a gravitational body force is applied while the left boundary is fixed. Reference: Linear Statics Benchmarks Vol. 1, NAFEMS Ltd., 1987.
