How to increase PSIM RAM usage

As you know, PSIM is a fixed point simulation method, so if you simulate it in more detail and longer, the amount of data increases.
And when this data is checked in Simview, the RAM share increases in proportion to this amount.
So to avoid running out of RAM, I've prepared a PC with 100GB or more.
However, even if you don't use up all the memory, you get a message that you don't have enough memory.
It seems that the amount of memory that can be occupied by PSIM or SIMview itself is set.
I wonder if there is a way to adjust it or increase it further.
