I'm not sure but I guess the memories located by CFX are not enough for your simulation. Try to change the settings in CFX-Solver Manager/file/define run/ check the <show advanced controls>, change the <memory allocation fact> as <1.2x> or larger. Maybe it works.

I believe that ur machine is not having enough memory to run the problem. The gen yard stick is u need at least 1GB ram for running a 1/4 mil nodes with combustion. If it is Non reactive flow the it will be less.

Yes, that's my meaning. As my experiences, 0.5M hexa grids need 1GB memories, how about your case? if your RAM is enough, I don't know the reason for that error.
