CST - Can virtual RAM be used for memory shortage during CST simulation?

Hello all,

Kindly let me know if the virtual RAM can be used in place of a physical memory shortage? 

The core model that I use in my simulation requires atleast 85 GB memory. But my available physical memory is 64 GB. Though I increase my virtual RAM to 120 GB, it does not seem to be used by the CST Studio Suite simulator and it still says that the available physical memory is only 64 GB. For CST simulations, can the virtual memory be used or is there any settings in the software that help enable for using the virtual memory? Kindly help with your answers.
