Question

Hello,
I'm using Pressure boundary conditions. When I tried to control the start time of 'Pressure BC' using the Controls module. It has the following error:

The following error occurred in the Control 'c1' of type TimePeriod.

The desired parameter 'BCs::Pressure::load1/enable' was not located for the 'c1' object, it either does not exist or has not been declared as controllable.

The Settings of BCs and Controls are as follows:

# ===== Boundary Conditions =====
[BCs]
  [archor_x]
    type = DirichletBC
    boundary = '3'
    variable = disp_x
    value = 0
  []

  [archor_y]
    type = DirichletBC
    boundary = '3'
    variable = disp_y
    value = 0
  []

  [archor_z]
    type = DirichletBC
    boundary = '3'
    variable = disp_z
    value = 0
  []

  [Pressure]
    [load1]
      boundary = '4'
      function = '-1e6'
      displacements = 'disp_x disp_y disp_z'
    []
  []
[]

[Controls]
  [c1]
    type = TimePeriod
    enable_objects = 'BCs::Pressure::load1'
    start_time = '400'
  []
[]

Is there a good way to control the start time of Pressure boundary conditions?

Hello

COuld you use the function parameter to apply a 0 load then the expected load at the desired time?
You could use a PiecewiseConstant function for that

The Action creates the 3 BCs then does nothing else. If you have the syntax to control the BCs created by the action that's far as this goes

[jessecarterMOOSE]

The Action takes a control_tag parameter. Can I control the Action as a whole through that?

[GiudGiud]

Not currently. We could try that though it would not be very standard. We would just need to forward the control tag parameter from the action to the objects

[GiudGiud]

I'll take a look. It makes sense to me
