Intel i9 i9-14900HX w 32gb RAM is enough for run 3D CFD simulations

I sow an Acer Predator Laptop with Intel i9 i9-14900HX and 32gb RAM, can be enough to run locally 3D CFD simulations with 15-20M elements? With run I mean, do 2000-3000 iterations in maximum 9-10 hours.
Actually I have an i7 9750H with 16gb RAM and I can barely open a case file of that dimension, it's literally impossible run a simulation.

I think you are going to need about 64GB of ram for 20 million cells.

20 million hexmesh need over 50GB 。if your case have mutiphase or use coupled.the num of memory use will be increased as well
