Alternatively, the 3x3 rotation matrix can be defined directly in the input file. The initial rotation is performed if the user provides arguments to the three Euler angle parameters the Bunge Euler angles provided in this class are used to perform passive (from the sample to the crystal) rotations using the extrinsic convention to build the rotation matrix. ComputeElasticityTensor also rotates the elasticity tensor during the initial time step only this class does not rotate the elasticity tensor during the simulation.

The material ComputeElasticityTensor builds the elasticity (stiffness) tensor with various user-selected material symmetry options.
