Options¶

In the three superordinated categories Appearance, Memory, and Miscellaneous there are several basic settings selectable. Firstly, in Appearance the font, its size, and the window colors of the DP_MICRESS layout can be chosen.

Secondly, Memory contains important features providing a smooth operation (See Figure 4.34).

• Maximum memory usage for timestep caching
  limits the amount of memory which will be used for caching time steps in main memory which are shown before. Raising this limit will smooth the stepping through time steps, esp. for large datasets.
• Don’t cache timesteps which are larger than (% of cache memory)
  This parameter allows to control the granularity of the time step cache. It depends on the size of the data which percentage of cache memory is a useful setting. The pretty small default value is chosen to hinder few large time steps taking the whole cache memory.
• Temporarily uncompress files which are larger than (MB) This is disabled by default. However, for large files with a low compression rate (e.g. concentration data), it might be beneficial to decompress them once before showing them. This is always a trade off between time for disk operations against time for decompressing data.

Thirdly, the Miscellaneous settings contain the option to hide confirmation requests such as 'Do you really want to exit Display Micress?'. This rubric is also handy in terms of hotkeys, presented in chapter Hotkeys. Once a part of a hotkey is entered it can be complemented for 2 seconds. The Time between frames in animation (seconds) refers on the possibility to make a video out of the simulation. When filming the on-going simulation the time space between two simulation steps is fixed. So the video seems more fluent or rather slowly for a detailed observing.
