using the -jvmargs tag you can check the default java heap size when launching STAR-CCM+


The java heap size can vary depending on the operating system of the client.  This could cause issues with java exceptions when running a macro on one system or in batch mode, which worked on a different operating system.
“Path_to_install”/star/bin starccm+ -jvmargs -XX:+PrintFlagsFinal | grep MaxHeapSize
