.Buildings.Fluid.FMI.FlowSplitter_u

Information

Block that takes as an input the inflowing fluid at the port inlet and a vector of control signals for the mass flow rates u. The mass flow of all outlet ports i is set to the value of u[i] m_flow_nominal[i]. If the inflowing mass flow rate at the port inlet is not equal to the sum of u[i] m_flow_in[i], the simulation stops with an assert.

Assumptions and limitations

The mass flow rates at all outlet ports must be non-negative. Reverse flow is not yet implemented. If either of these limitations are violated, then the model stops with an error.

Revisions

• March 18, 2024, by Michael Wetter:
  Added causality.
  See IBPSA, #1853.
• January 18, 2019, by Jianjun Hu:
  Limited the media choice. See #1050.
• June 9, 2016, by Thierry S. Nouidui:
  Removed assert() statement which was triggered when the model was exported as an FMU depending on the execution sequence of the master algorithm.
• May 27, 2016, by Michael Wetter:
  Replaced outlet[i].forward = inlet.forward; with a connect statement as accesses to composite components other than records are not allowed. This was done for JModelica compliance.
• July 28, 2015, by Thierry S. Nouidui:
  Corrected wrong assert statement.
• April 29, 2015, by Michael Wetter:
  Redesigned to conditionally remove the pressure connector if use_p_in=false.
• April 15, 2015 by Michael Wetter:
  Changed connector variable to be temperature instead of specific enthalpy.
• November 20, 2014, by Michael Wetter:
  First implementation.
