Hi,

I just came by chance accross this old post. I have experienced recently the same issue:
I do a run, where I use the Navier-Stokes Solver and calculate the loads. Then I restart from this, and in my second run I am not running Navier-Stokes, I only need the loads. The userfunction which uses them can't find them. They are not found in Model % Variables anymore (see code below, I get the error message 'Need >Calculate Loads = Logical True<. Flow Load not found').
So apparently FlowLoads are saved during the restart, but are not found by Model % Variables unless the Navier-Stokes Solver is present in the sif-file.
I'm not sure if that is wanted?
Putting Navier-Stokes with Exec=Never in the sif-file works, and also saving the loads as variable and passing directly this variable to the userfunction helps (but the latter makes loosing the benefit of passing them automatically).

Code: Select all

! Get the Stokes loads
  !---------------------------
  FlowLoadsName = GetString( Model % Solver % Values , 'Flow Solver Name', GotIt )  
  IF (.NOT. GotIt) THEN
     WRITE(FlowLoadsName,'(A)') TRIM(FlowSolutionName)//' Loads'
     WRITE(Message,'(AA)') 'Using default name for flow solution: ', &
          FlowLoadsName
     CALL WARN(FunctionName,Message)
  END IF
  FlowLoadSol => VariableGet( Model % Variables, TRIM(FlowLoadsName) )
  IF ( ASSOCIATED( FlowLoadSol ) ) THEN
     FlowLoadPerm    => FlowLoadSol % Perm
     FlowLoadValues  => FlowLoadSol % Values
  ELSE
     CALL FATAL(FunctionName,&
          'Need >Calculate Loads = Logical True<. Flow Load not found')
  END IF

  END IF
I don't think the main problem is not specific to her own userfunctions or her recent changes in sif-files.
