I am relatively new to NX. When I do a linear statics simulation, it looks like that not all resources of my PC are used. I read that Nastran is a very IO intensive Programm, but sometimes my disk usage is at just 10-30 %. Do I have wrong software configurations, do I have too less RAM (8 GB I know it is not much) or is it any different problem?
Please find the picture of the Task Manager attached.
There is a lot of old discussions regarding this in the forum, including one started by me, try this link
My personal experience is that Nastran uses surprisingly little of the resources on my workstation PC. I bougth this strong workstation PC with a lot of RAM and SSD, but see small performance difference compared to my older laptop.
Having said that, there is a lot of tip regarding this on the forum. Try a search.
