  Hi,
  I am practing to simulate thermosiphon systems. i have selected a reseach paper's operating conditions to start my simulation.
  The operating conditions reported in the paper, as a negative gauge pressure value of (-86084.7 [pa]), i want to know what value should i insert in the place of operating pressure at the operating conditions task.
  please, explain me how should i indentify or calculate the correct operating pressure value for the simulation from the given gauge pressure.

  From reading the documentation what value do you think is suitable?
