A FCBIS TRIANGULAR ELEMENT FOR INCOMPRESSIBLE FLUID FLOWS

  • 摘要: 结合流动条件插值和分裂算法的优点,提出了黏性不可压流体基于流动条件插值的分裂算法(FCBIS),构造了相应的平面三角形单元,推导了相应的有限元公式,并编制了计算程序.数值算例表明所构造的单元有效、准确.

     

    Abstract: Taking advantages of the best features of flow-condition-basedinterpolation and split scheme, this paper proposes a flow-condition-based interpolationsplit scheme (FCBIS). A two dimensional triangle fluid element is builtand a corresponding program is developed. The solution procedure isdiscussed and the numerical example solution is given to illustrate theefficiency and accuracy of the procedure.
