1. Best Practice Hardware and Software Recommendations

8. Conclusion General guidelines for a computer on which FEM calculations will be performed in Creo : • Make sure your drivers are updated (processor and graphics card) • Processor For this computer you can have more cores High clock frequency Processor with high cache memory • RAM See guide on Knowledge Base : Creo Simulate – Information about RAM and SolRAM

2. Performance This guide presents guidelines and recommendations for hardware for a CAD - computer that is to be used for Creo Parametric . Primarily it is five parts that affect the overall performance of a computer when using a PTC CAD - application : • Processor(s) – affects how fast the computer performs calculations • RAM – how much data that is available for the processor in a fast working memory • Hard drive – affects the time it takes to open a model and the time it takes to save to disk • Graphics card – affects how fast models are displayed on the screen • Settings and software

7. Conclusion General guidelines for a CAD - computer (where no FEM calculations are performed) : • Make sure your drivers are updated (processor and graphics card) • Processor 2 - 4 cores High clock frequency Processor with high cache memory • RAM Minimum 16 GB • Hard Drive SSD, minimum 256 GB • Graphics Card According to the PTC Platform Support Note ! Reference documentation and platform guides can be found here: https ://

4. RAM The Random Access Memory (RAM) is a form of computer data storage that is faster to read/write to than the hard drive . RAM is used by the processor to store/access data faster during calculations . We have opened what can be considered a very large assembly in Creo Parametric, and approximately 8 GB of RAM was used . Although PTC recommends a minimum of 4 GB RAM we would say that 8 GB is a bit on the lower side, so choose more than that .

3. Processor The general concept is that more cores results in better performance . This is inaccurate for Creo Parametric since the performance also depends a lot on the programs ability to use the available cores . Creo Parametric generally only uses one core . Hence, the clock frequency per core is of great importance . If you use Creo simulate you can take advantage of several cores while running simulations . The clock frequency is the speed of which every core performs calculations . Example: • Computer A has two cores with 3.5 GHz frequency each. • Computer B has 4 cores with 2.6 GHz. Since Creo only uses one core the difference is 0.9 GHz if both computers are used to their maximum capacity with Creo. Computer A is almost 50% faster than computer B.

5. Hard Drive An SSD drive is recommended for the use of Creo Parametric . An SSD - drive (Solid - State Drive) is intended to fill the same purpose as a hard drive, but is built without the moving parts that a mechanical hard drive is dependent on . An SSD - drive is therefore much faster, quieter, and less sensitive to impacts . An SSD - drive has a write and read capacity that is about six times higher than a mechanical hard drive . The biggest advantage is that it is a lot quicker to collect data with an SSD - drive . E xample: What takes 7.2 ms to collect from a hard drive can take less than 0.1 ms for an SSD

6. Graphics Card The graphics card affects how a model is shown in the graphics windows . Some of the common symptoms of problems with the graphics card are : • Failed to launch software • Premature exits during regeneration/ or selecting an icon • Experiencing graphics issues (glitches when rotating or moving the model) • Model not shown in the graphics area • Lines appear on model or drawing that should not exist • Creating dimension, repainting, or refreshing is slow • Drawing view disappear when zooming • Black lines appear on model when rotating or moving the model • ... and more Please make sure that you are following the guidelines for Platform Support from PTC and that your graphics driver is updated to the latest version .
