Yes, I understand that.

I guess I will have to buy one. Can anybody suggest me what I could buy? I mean. The GPU will not be used for simulating, "only" to render results.

Is the dedicated memory the only parameter I should care about? The GPU I currently have is a Nvidia Quadro, I don't really know if I could also use a GeForce, for example. RTX I understand is also an option, being also for professional use.

If the memory is the only important thing, I could also get a cheap Intel Arc...

Any input would be appreciated.

Also regarding the Nvidia control pannel settings. Any idea about what is the best performance settings for SpaceClaim and Fluent Standalone??

Thank you very much in advance. I don't have much knowledge about GPU world at all...

Kind regards.
