subroutine usalin
!================

!===============================================================================
!  Purpose :
! --------

! --- User subroutine dedicated to the use of ALE (Arbitrary Lagrangian Eulerian)
!     method :
!
!          Here one defines parameters and input data dedicated to the use ALE
!          method
!

!     Type: i (integer), r (real), s (string), a (array), l (logical),
!           and composite types (ex: ra real array)
!     mode: <-- input, --> output, <-> modifies data, --- work array

iale = 1

! EXAMPLE_CODE_TO_BE_ADAPTED_BY_THE_USER_START

! --- Number of iterations for fluid initialization. Contrary to ntmabs (for example)
!     nalinf is not an absolute iteration number, meaning that in case of
!     restart calculation nalinf corresponds to the number of iterations
!     for fuid initialization beginning from the first current iteration of
!     the calculation restart. In general nalinf = 0 in that case.

  nalinf = 75

! EXAMPLE_CODE_TO_BE_ADAPTED_BY_THE_USER_END

! EXAMPLE_CODE_TO_BE_ADAPTED_BY_THE_USER_START

! --- Maximum number of iterations in case of implicit Fluid Structure Coupling with structural
!     calculations (internal and/or external(i.e. using Code_Aster)). NALIMX = 1, in case of
!     explicit FSI algorithm.

nalimx = 15
