Hi,

I want to ask if somebody could help.

I want to upgrade my PC

Should I upgrade CPU, RAM, or SSD if I want to speed up my running.

Is there anybody know what each of these part affect for running?

    If your models are heavy, I would say CPU, RAM and SSD !

    If your PC is older than 3 years, don't upgrade but replace it!

    for OptiStruct, usually RAM is the more important, as having enough memory would allow you to use in-core mode, wwhich runs faster.

    But of coarse a good SSD and a fast CPU helps.

     

    RAM >> larger models require more RAM memory to run efficiently

    SSD >> a good SSD will speed-up computations when large data blocks need to be used (this tends to be less important if enough RAM is available)

    CPU >> newer CPUs are more efficient. But number of core's are not so heavily important for OptiStruct. You can have a gain, but it also depends on how many licenses you have available and kind of model. Explicit codes tend to take more advantages.

     

    I agree with the above replies, and depending on how old ytour machine is maybe s better to replace it.
