    • RE: 气动中心的NNW软件使用体验

      @TINGHAIK 下载了还没用过,感觉算气动应该挺不错的了,看里边的案例做的还挺有意思的,不过界面上应该还可以下点功夫,不涉及工程计算用现有的工具可以了。

    • RE: 关于二维模型的计算,这两种snappyHexMesh方法有什么不同,应该采用哪一个?

      @Samuel-Tu 最近几天看了看salome,感觉照着官方的tut操作一遍,使用上应该没啥问题了,除了操作有点繁琐,其他感觉用起来还挺顺手的,我先学学,学会了可能在b站录个系列教程。
      salome的第一个tut就可以创建只有一层的网格,楼主有需要可以自己去看看。

      preCICE很amazing,用好了应该比自己改求解器简单高效 https://www.bilibili.com/video/BV1iT4y1P7e7/

      cfmesh好像能定义不同方向不同的加密

    • postProcess 输出ddt(U)和div(phi,U)

      想在计算完成之后输出ddt(U)和div(phi,U)
      直接运行postProcess -func 'ddt(U)', 提示ddt is not supported with the postProcess utility FOAM Warning : functionObjects::ddt ddt(U) failed to execute.
      运行pisoFoam -postProcess -func 'ddt(U)' 提示in command line pisoFoam -postProcess -func div(phi,U) Placeholder value is <fieldName>
      想用coded输出也一直没成功,因为已经有计算结果了,不想动求解器:

      libs    ("libutilityFunctionObjects.so");
      type    coded;
      name    ddt;
      codeWrite
      #{
      
      const volVectorField& U = mesh().lookupObject<volVectorField>("U");
      //const volScalarField& phi = mesh().lookupObject<volScalarField>("phi");
      
      // Write
      volVectorField ddt("ddt", fvc::ddt(U));
      ddt.write();
      
      #};

      @Stan同学 这个看起来比IBM啥的简单一些,我看有人也用它算心脏的流动,坐等出教程,哈哈哈

    • RE: 流体网格的更新问题

      @Stan同学 可以看看这个流固耦合的接口precice

      preCICE is the leading open-source coupling library for partitioned multi-physics simulations, including, but not restricted to fluid-structure interaction and conjugate heat transfer simulations.

      Partitioned means that preCICE couples existing programs/solvers capable of simulating a subpart of the complete physics involved in a simulation. This allows for the high flexibility that is needed to keep a decent time-to-solution for complex multi-physics scenarios.

      The software offers convenient methods for transient equation coupling, communication, and data mapping.

    • RE: of2006安装完找不到paraview和paraFoam

      今天解决了这个问题
      先在$WM_THIRD_PARTY_DIR编译paraFoam并执行wmRefresh
      到$WM_PROJECT_DIR/modules/visualization路径下执行 ./Allwclean && ./Allwmake && wmRefresh
      转到$WM_PROJECT_DIR路径下执行 ./Allwmake && wmRefresh

      命令:

      cd $WM_THIRD_PARTY_DIR
      ./makeParaView
      wmRefresh

      cd $WM_PROJECT_DIR/modules/visualization
      ./Allwclean && ./Allwmake && wmRefresh

      cd $WM_PROJECT_DIR
      ./Allwmake && wmRefresh
