Revisions
-
May 5, 2023 by Hongxiang Fu:
Removed a self-dependent input binding in the function checkState.
This is for
#3384.
-
March 24, 2020, by Kathryn Hinkelman:
Expand error message for checkState and added absolute error as input.
-
September 16, 2019, by Yangyang Fu:
Reconstruct the implementation structure to avoid duplicated codes for different media.
This fixes #1206.
-
June 6, 2015, by Michael Wetter:
Changed type of T from
Modelica.Units.SI.Temperature to Medium.Temperature.
Otherwise, it has a different start value than BaseProperties.T, which
causes an error if
BuildingSystems.Media.Examples.WaterProperties
is translated in pedantic mode.
This fixes
#266.
-
October 16, 2014, by Michael Wetter:
Removed call to setState_dTX as this
function is physically not defined for incompressible media.
-
December 19, 2013, by Michael Wetter:
First implementation.
