Hello, I am new student in CFD, thus I am reading research papers and try to simulate it in my own PC to just practice my skills, the question is could I run simulation on my own PC Dell G5 with processor i7 6 cores and RAM 16GP, the case is 3D cavity (Fuel-Air) mixing in supersonic combustion with total element on Ansys Mesh (17278118) ?

or this will be harmful simulation to my machine ?

Will it cause your PC to explode? Unlikely.


Depending on the number of transport variables needing to be stored though, I don't think you can run a 17 million cell case with only 16 GB of RAM.

I would even go a bit further and say that not only will your PC not explode, it will also not take any damage from doing what it is supposed to do
So don't worry about that. PCs these days have protection mechanisms built-in. Limiting sustained power draw, reducing clock speeds when overheating... it is rather hard to damage components by just running regular software.

As was already stated, the model is probably too large for 16GB RAM. If you just want to practice, you can run the same case with a coarser mesh. Maybe even try to figure out a more efficient meshing strategy that gets good results with fewer cells.
