      A generalized trapezoidal rule is used and the choice of integration scheme is controlled by the Euler parameter (theta). The time integration scheme can be changed by using a simple command snippet inside ANSYS Mechanical. TINTP,,,, where, theta = 1.0 uses Backward Euler rule (default); = 0.5 uses Midpoint or Crank-Nicholson
