Running a Global Model
To run large or Global scale simulations in STEM, you will need to increase the heap size available to the STEM JVM.
The method for doing this depends on which operating system you are using:
Mac OS X:
From the folder you unzipped STEM, access the STEM.ini file located under STEM.app/Contents/MacOS. Open the file in a text editor and change the line -Xmx1024M to a larger number. For instance, to give 4 GB of maximum heap size to the STEM application change the line to -Xmx4096M.
Linux/Windows:
From the folder where you unzipped STEM (same location where the STEM executable is located), open the STEM.ini file and modify the -Xmx1024M line to increase the maximum heap size to any value you desire. For instance, to give 4 GB of maximum heap size to the STEM application change the line to -Xmx4096M.
Please Note
To set the maximum heap size to anything larger than 1024 MB, you must be running a 64 bit operating system.
