Ffunction(t, x, earthPressureCoefficients, zeta, delta, eps_x, eps_y)

Calculate right hand side of the differential equation : dx/dt = F(x,t) F is discribed in Hutter 1993.

Parameters

• t (float) – curent time

• x (numpy array) – initial condition, column vector of size 4

• earthPressureCoefficients (numpy array) – earth Pressure Coefficients

• zeta (float) – slope angle

• delta (float) – friction angle

• eps_x (float) – scale in x dir

• eps_y (float) – scale in y dir

• Returns

• F (numpy array) – column vector of size 4
