How to pass additional JVM arguments to the simulation on execution?
Create an ASCII file in your user home directory named omsrt.properties. On Windows it is usually the directory C:/Documents and Settings/<USER>, on Linux it is /home/<USER>. Create a property entry in ${HOME}/omsrt.properties using the jvm.args key, that has the desired JVM options as value.
As an example the following setting will increase the initial and maximum heap size for a model to execute to 256 MB.
${HOME}/omsrt.properties:
jvm.args=-Xms256M -Xmx256M
Note that this setting as specified in omsrt.properties applies to all simulations.
