  Dymola 2015 Release Notes  41 
3.11  Appendix – Installation: Hardware and Software 
Requirements 
Below the current hardware and software requirements for Dymola 2015 are listed. 
3.11.1  Hardware requirements/recommendations 
Hardware requirements 
•  At least 1 GB RAM 
•  At least 400 MB disc space 
Hardware recommendations 
At present, it is recommended to have a system with an Intel Core 2 Duo processor or better, 
with at least 2 MB of L2 cache. Memory speed and cache size are key parameters to achieve 
maximum simulation performance. 
A dual processor will be enough; the simulation itself uses only one execution thread so 
there is no need for a “quad” processor. 
Memory size may be significant for translating big models and plotting large result files, but 
the simulation itself does not require so much memory. Recommended memory size is 2-4 
GB of RAM for 32-bit architecture and 3-6 GB of RAM for 64-bit architecture. 
3.11.2  Software requirements
