[求助] 用polyflow做模拟挤出，出现错误？

用polyflow做模拟挤出，材料选材料库中的材料，进行广义牛顿非等温流体分析，出现错误？

1.Update failed for the Solution component in Fluid Flow - Extrusion (Polyflow).  The Polyflow Solver for system Fluid Flow - Extrusion (Polyflow) exited with an error. No results file is available.Detailed information can be found in the listing file for the run, which can be viewed by selecting [Listing Viewer] from the Solution component.

2.(DP 0) Summary of the simulation:

      The computation failed.

   *  Expert tool diagnostics  *

   The problem Preprocessors 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 2.2722e-007.
   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 Inflow introduced by the power
   law index (n) of the viscosity law.  The value of the power law index
   is 2.2722e-007.

   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 = 2.272e-007
      - S-final = 1.0
      - Initial increment = 2.8402e-007 = 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.
