Re: [EnergyPlus_Support] Re: Phase change material


I use a GNU compiler bundled into an IDE called simply fortran. A free trial can be downloaded on their website: <http://simplyfortran.com/>http://simplyfortran.com/ Jeff the developer provides great support. The latest E+ source folder from Florida solar energy center has a make file for simply fortran, but I have not used it. 
Rather I researched and found these that it works for E+ with these compiler flags: -cpp -ffree-line-length-none -Wtabs -fbacktrace -Wno-align-commons -w

For the last few months I have been working on a new object called Material Property Dual Curve that provides hysteresis modeling capabilities.  (Thought of naming it Material Property Phase Change Hysteresis, but did not due to the common understanding that PCM's that express hysteresis have poor performance)

However you will notice there is no EnergyPlus.exe in the folder.  In order to run this you have to use the JESS server by Yi Zhang. You can find out how to use JESS here if you are not familiar: <http://www.jeplus.org/wiki/doku.php?id=docs:ep_launch>http://www.jeplus.org/wiki/doku.php?id=docs:ep_launch
(To use JESS you have to get an account)

Hello,
