ForceToStress Solver

General Informations

  • Solver Fortran File: ForceToStress.f90
  • Solver Name: ForceToStress
  • Required Output Variable(s): Stress (user defined)
  • Required Input Variable(s): Force
  • Optional Output Variable(s): None
  • Optional Input Variable(s): None

General Description

SIF contents

For a given boundary, this solver computes the nodal stress equivalent to a given nodal normal force. This can be used also to infer the flux from the knowledge of a debit.

Solver 1
  Equation = "Navier-Stokes"
  Stabilization Method = String Stabilized
  Flow Model = Stokes

  ...

  Exported Variable 1 = Flow Solution Loads[Fx:1 Fy:1 Force:1 CEQ Residual:1 ]
  Calculate Loads = Logical True
End

Solver 2
    Equation = "ForceToStress"
    Procedure = File "./ForceToStress" "ForceToStress"
    Variable = String "Stress"
    Variable DOFs = 1

    Linear System Solver = Direct
    Linear System Direct Method = umfpack
 End

! Solve this for body Id 2 (=boundary 3 here)
Equation 2
  Active Solvers(1) = 2
End

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Boundary Condition 3
  Target Boundaries = 5
  Body Id = 2
  ...
End
