Does CFD need GPU?
You don’t need mega GPU power for CFD, FEM, FEA, CAD or any of those assorted engineering tools. Some softwares may be able to utilise CUDA or OpenGL cores, which are more numerous on workstation gpus such as the Quaddro and Firepros, but the list of softwares that can make use of the cores is limited at best.
Is 4GB RAM enough for Ansys?
For Installation you will need 4GB RAM. ANSYS Mechanical is I/O intensive application so you may need much more RAM to run the Solver. We suggest ~16GB RAM to run the application. ANSYS has multiple other software from other domain in its suite ; Fluent, CFX, HFSS, Maxwell, Ensite, Redhawk, SpaceClaim etc.
Can i3 run Ansys?
Yes you can but the complexity of the project you intend to work on is of concern. Your Ram is also important. I use a laptop with similar features (4Gb ram with large hard disk), and I run both Solidworks 14 and Ansys 17 but limits the scale of project I use it for, most times academic.
