!COUPLE¶

Definition of coupled surface (Used only in coupled analysis)

Parameters¶

TYPE =    1: One-way coupling          (FrontISTR starts by receiving data)
          2: One-way coupling          (FrontISTR starts by sending data)
          3: Staggered two-way coupling (FrontISTR starts by receiving data)
          4: Staggered two-way coupling (FrontISTR starts by sending data)
          5: Iterative partitioned two-way coupling  (FrontISTR starts by receiving data)
          6: Iterative partitioned two-way coupling  (FrontISTR starts by sending data)
ISTEP =   Number of steps
          From the start of the analysis through the number of steps specified here, the fluid force is increased by multiplying it by a linear function from 0 to 1,
          and thereafter the input fluid force is applied as-is
WINDOW => 0 : Apply the fluid force multiplied by the window function (*)

(*) \(\frac{1}{2}(1 - \cos\frac{2\pi i}{N}),(i: current step, N: total number of steps in the current analysis)\)
