请教关于Excite多体动力学计算问题

流星雨

我在做Excite多体动力学计算，运行Simulation时，提示如下错误：

$ Error (Code 871001)
The iteration in this time step is diverging and a reduction of the
time step size is not possible.
The calculation must be stopped.

User action: (1) Decrease the minimum (and maximum if necessary) time step size.
              (2) Decrease the accuracy parameters for the calculation
                  to increase the stability of the solution procedure.
                  (I.e. decrease RESCTR EPSU ... EPSR ... EPSE ...)
              (3) Check your calculation model.
              (4) If this occurs near the calculation start,
                  check the initial conditions of your model.
              (5) Check the Finte Element models of the bodies for
                  - small masses and moments of inertia
                    (esp. at reference points)
                  - small stiffness coefficients
                  - errors in the definitions of the degrees of freedom
                    (e.g. displacements in local coordinate systems)
请问这里的Code 871001和RESCTR EPSU ... EPSR ... EPSE ...分别是指什么？我又该做如何调整？谢谢！
