Information

This example demonstrates how the pump curves changes for different (constant) input signal y. If y ≥ delta = 0.05, the pump curves are polynomials. For y < delta = 0.05, the pump curves convert to linear functions to avoid a singularity at the origin.

• December 2, 2016, by Michael Wetter:
  Changed the valve opening signal to not take on zero as otherwise pum.port_a.p is negative, violating the min attribute on the pressure variable.
  This is for #606.
• March 11, 2016, by Michael Wetter:
  Reformulated model for OpenModelica.
• January 22, 2016, by Michael Wetter:
  Corrected type declaration of pressure difference. This is for #404.
• June 14, 2015, by Filip Jorissen:
  Set constant speed for pump using a parameter instead of a realInput.
• March 24 2010, by Michael Wetter:
  First implementation.
