GetHydrostaticLoads Solver

General Informations

  • Solver Fortran File: GetHydrostaticLoads.f90
  • Solver Name: GetHydrostaticLoads
  • Required Output Variable(s): Fw (user defined DOFs=2 in 2D, 3 in 3D)
  • Required Input Variable(s): External Pressure
  • Optional Output Variable(s): None
  • Optional Input Variable(s): None

General Description

For a given boundary, this solver computes the equivalent nodal force induced by a pressure on the surface (read from the keyword External Pressure). The result is a force vector (Fx,Fy) in 2D and (Fx,Fy,Fz) in 3D.

SIF contents

Solver 1
  Equation = Fw
  Variable = Fw[Fx:1  Fy:1 Fz:1]
  Variable DOFs = 3
  Procedure = "ElmerIceSolvers" "GetHydrostaticLoads"
End

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

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Boundary Condition 3
  Target Boundaries = 5
  Body Id = 2
  External Pressure = Real 0.1
End

Examples

In this example, a pressure applied on a boundary is first integrated to get nodal force using the GetHydrostaticLoad, and then the pressure is recovered using the ForceToStress Solver.
