Till now I am using ansys cfx to analyse the wind domain. Meshing type is tetrahedral. But for every reviewers is saying that tetrahedral is backdated so use another meshing type. My laptop in i3 with 8 gb ram. Is it possible to do analysis with ICEM CFD?? Where will I get some tutorial for ICEM CFD. Thanks in advance.

ICEM CFD is just another mesher. You cannot use it as CFD-solver.

Moreover, ANSYS CFX is a node solver, already since 2000 (approximately) when it started as CFX-5. This is comparable to cell centered solvers like Fluent or Star-CCM+ when applied on a polymesh (not a tet-mesh). So, it is not backdated at all.

impossible to say. I3 is not very fast. So, if you can wait for it, then the memory of your laptop sets the limits.

In my experience ICEM is the most memory efficient meshing software around. If there is any software which will handle a large mesh on limited hardware it will be ICEM.

Tetrahedron is not without benefits. At least for some engineering problems, the benefits of tetrahedron are convenient, and the error of calculation results is not as large as imagined. I suggest that you first deal with this problem by automatically generating tetrahedrons.
