What is NX Nastran used for?
NX Nastran enables engineers and designers to rapidly evaluate many more design concepts than can be accomplished with physical prototypes. Simulation allows engineers to better understand and optimize design tradeoffs for quality, cost and performance.
How can I make my Nastran faster?
Other tips to speed up your NX Nastran simulation include:
- Using an iterative solver where there are a small number of load cases and a large Front Size.
- Restart from a previous solution if the difference from the previous run is a different output.
- Learn to read . f04 files so you can understand performance.

How can I improve the performance of NX Nastran?
The Windows OS needs space for itself, and will use extra memory to cache the disk I/O for applications like NX Nastran that can help improve the performance. If you over allocate system RAM for NX Nastran you can actually hurt the overall system performance since the memory available for the I/O Cache is reduced.
What do I need to know before starting a NX tutorial?
The instructions are intended for use with NX 10 and NX Nastran 10. Before starting a tutorial, set your NX role to Advanced. You should also be familiar with basic NX concepts and tasks. For more information about the tasks and concepts discussed in these tutorials, see the Advanced Simulation online help.
What is the size of the NASTRAN executable?
NX Nastran actually comes with two different 64 Bit executables, the standard LP-64, and the optional ILP-64 executable. The LP-64 executable still uses 32 bit integers, and is limited to 8 GB of RAM.
How much RAM do I need to run a NASTRAN model?
But if your model does not need more than 8 GB of RAM for the solution, the standard LP-64 executable will be faster. Starting with NX Nastran 10.0, the solver allocates 45% of available RAM to the solver executable.
