Problem with heap space when compiler is called by other software.

Hello,

I am calling the visual studio compiler through ANSYS Fluent and when I try to compile I get the error:

The compiler is out of heap space

Is there a compiler flag I can use to increase the available heap space when compiling?  The file I am compiling is massive because it has 2000 double vectors with 1000 elements each, but I have 128GB of RAM on this system so I think it can handle it.  I have seen the linker flag - /HEAP:1000000 but this does not work as a compiler flag.  I do not see where I can pass flags to the linker in the ANSYS Fluent interface.

Thanks
