C    WE WANT THE FIRST MATERIAL AXIS TO BE +45 DEGREES FROM THE FIRST SIDE
C    OF A GIVEN ELEMENT AND ALSO TO BE IN THE PLANE OF THE SHELL
C    (IE, PERPENDICULAR TO THE SHELL NORMAL). THE UNIT VECTOR THAT
C    SATISFIES THESE REQUIREMENTS IS IN THE GLOBAL DIRECTION
C    X=(.091752,.908249,.4082486).

C    NOW COMPUTE ANGLE (`THET') BETWEEN THIS DESIRED
C    FIRST MATERIAL DIRECTION AND THE FIRST BASIS DIRECTION CHOSEN BY ABAQUS.
