pyyeti.ode.SolveExp1.tsolve

SolveExp1.tsolve(force, d0=None)[source]

Solve time-domain 1st order ODE equations.

Parameters:

  • force (2d ndarray) – The force matrix; ndof x time

  • d0 (1d ndarray; optional) – Displacement initial conditions; if None, zero ic’s are used.

Returns:

  • A record (SimpleNamespace class) with the members

  • d (2d ndarray) – Displacement; ndof x time

  • v (2d ndarray) – Velocity; ndof x time

  • h (scalar) – Time-step

  • t (1d ndarray) – Time vector: np.arange(d.shape[1])*h
