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 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 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. |
