User manual

The default is that Dymola start to warn 30 days before the license is expiring, and starts in

demo mode if the license is not found or invalid.

Consider a user wanting to have the first warning 5 days before the license is expiring, and

wanting to terminate Dymola if the license is not found or invalid. Assuming a 32-bit

Windows computer with Dymola at default location, Dymola could be started with the

following command line using the Command Prompt in Windows:

"C:\Program Files\Dymola 2014 FD01\bin\Dymola.exe" /days -5

The value (5) controls how many days that should be left to expiration when warning, and

the minus before the value is added if Dymola should terminate if the license is not found or

invalid.

“-” can be used instead of “/“; the example above will then be:

"C:\Program Files\Dymola 2014 FD01\bin\Dymola.exe" -days -5

1 day is the minimum start time for warning of license expiration; the warning cannot be

completely disabled.

3.4.3 Hardware requirements and 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.

3.4.4 Software requirements

Microsoft Windows

Dymola versions on Windows and Windows operating systems versions

Dymola 2014 FD01 is supported, as 32- and 64-bit application, on Microsoft Windows XP,

Windows Vista and Windows 7. Since Dymola does not use any features supported only by

specific editions of Windows (“Home”, “Professional”, “Enterprise” etc.), all such editions

are supported if the main version is supported.
