hello . i am sorry for my lack of simple knowledge . i am an undergraduate student who just bought a new pc and i was wondering if i could use it to run fluent analysis . i am afraid that running fluent calculations would ruin my pc so i wanted to ask your opinions first . I usually work in university on 2d projects with 100 thousands elements for transient projects that take about one million iterations to finish a melting process .
my pc has
intel(R) Core(TM) i5-10400F CPU @ 2.90GHz
16 ram
GeForce GTX 1660 SUPER (eventhough i don't know how to use it in calculations)
is that good to run this analysis without any harm to my pc ?
also what about more complex analysis like flow over a car or a 3d plane . could it harm my pc ? is there a way to ensure its safety?
thank you alot in advance

This might not be an adequate answer, but I'm pretty certain it can't "ruin" your computer. 100 thousands elements for transient simulation really isn't that demanding (compare to other transient simulations that are being ran).
But beware of how many number of cores you use for the parallel computation.
I think your CPU is 6core, so I would personally use 4-5 max if I want to do other things on the computer while running the simulation (word,excel, etc., non-CPU heavy software).

Also it may take a while to run the simulation depending on the complexity of your model. As an example, my 900k+ element transient simulation on my office workstation (6cores) takes 1-2 days.
For 3D cases, for a car, it really depends on how accurate you want to be. Some simulations for a 3D car takes months to years using a HPC (supercomputer). And I highly doubt you'll get any accurate results with it if you reduce the # of elements to run it on your computer.

Hi man,

By itself, fluent won’t damage your pc. However, as you will be for sure stressing your processor, you must make sure the temperatures are in check. So download a temperature monitoring software ( there are many) and see what temps the CPU reaches while calculating. Anything <= 75 C is super fine. However, if you reach, say, 90 C, I would avoid running 3-4 days of simulation full time.
