Re: Using computer cluster to calculate simulation
It is news to me if any sort of cluster use is supported, in fact I know it is not supported. The program supports the use of multiple cores on a single machine. It does have the option to use a "remote solver" but this as well is multiple cores on a single box. The scaling gets pretty weak after about 4 cores.

Re: Using computer cluster to calculate simulation
I think what you are referring to is the ability to run separate simulations on other computers remotely.
It does not split the work of a single model, but you can run one model on computer "A" while another model is run on computer "B". This requires that computer "B" also have a valid license.

Re: Using computer cluster to calculate simulation
Thank you for the answers it must be a link to be able to do simulations on other machines.
But I'm pretty interrested in doing calculations on multiple cores, i'm running 2008 sp3, and I'm pretty sure that it does not use multiple cores do you have to enable it somewhere?

Re: Using computer cluster to calculate simulation
I am pretty sure that Floworks 2008 did support multiple cores, if not for sure it does it in 2009 and later releases.

Re: Using computer cluster to calculate simulation
It only uses multiple cores during certain portions of the calculations. In FloWorks (both 2007 and 2009) it is mostly single core (in performing radiation calculations it will use multiple cores to refine rays, then reverts back to single core for other aspects of each iteration). It all depends on the part of the simulation it is currently working on.
I have similar jumps during stress simulations also (2009), it runs along at 1 core for a time then jumps to 5 cores for a time and alternates back and forth.
I have never seen an option to enable or disable this, I believe it automatically uses more cores as the type of calculation allows. You could limit this through windows setting of processor affinity (not sure why you'd want to) but it should start out with the ability to use all available cores.

Re: Using computer cluster to calculate simulation
This topic came up a couple weeks ago except that it was refered to as a "render farm". I'm not sure if there is any additional information in the original thread but here it is:

Re: Using computer cluster to calculate simulation
Thank you for the answer however they seem to be needing it for rendering and not simulations so they found a way by exporting it or something.

Re: Using computer cluster to calculate simulation
You can consider lucky that stress/ flow simulation knows to use multiple cores, even they are on the same machine. Motion studies are still in the stone age

Re: Using computer cluster to calculate simulation
Thank you all for your feedback
I guess, we just have to wait till solidworks will use our processing power optimal
