[求助] polyflow 模拟逆向挤出出现问题

现用polyflow软件模拟逆向挤出问题 结果不能收敛,提示如下: ********************************
     *   Summary of the simulation  *
     ********************************

        The computation failed.


     ***************************
     * Expert tool diagnostics *
     ***************************

     The problem F.E.M. Task  1  has not converged.


     ***************************
     * Expert tool Suggestions *
     ***************************

     There is a non-linearity in problem Navier-Stokes 3D introduced by
     the power law index (n) of the viscosity law.  The value of the power
     law index is 0.75.
     The expert system suggests to use a Picard iterative scheme with a
     number of iterations about 30 or 40.

     There is a non-linearity in problem Navier-Stokes 3D introduced by
     the power law index (n) of the viscosity law.  The value of the power
     law index is 0.75.
     The expert system suggests to use an evolution for this parameter
     coupling with Newton-Raphson iterative scheme.  The evolution scheme
     must be the following :
        -   f(s) = 1/s
        -   S-ini = n = 0.75
        -   S-final = 1.0
        -   Initial increment = 0.9375 = n/0.8.

     If you can not define the evolution with those typical values of the
     evolution parameters, maybe your problem is not well defined.  Please
     check the setup of your simulations.
望遇到同样问题的虫友,解答或者共同探讨下.

可否请教下楼主用的是的ansys哪个版本,之前尝试下载安装了几个ansys,但是polyflow都不能用啊
