Following error can be obtained in FORTE Simulate if mesh is manipulated. (split, merge etc…) or if you want to display very large meshes: Exception in thread “AWT-EventQueue-0” java.lang.OutOfMemoryError: Java heap space The error can appear in DOS or linux console. It means that not enough heap memory is allocated to Java. 2 alternative solutions are proposed: Method 1: You can set the Java heap memory by changing the preferences in Forte Launcher. You can change the memory for Forte Simulate and for Forte Visualize. (by default 8 192 Mb is set) Method 2: You can modify Java heap memory by setting following environment variable. setenv FORTE_MEMORY -Xmx16g That would increase the java heap memory to 16 GB. 10 GB is usually recommended. This aspect is commented in Appendix A.2 of Forte user’s guide.
