Dialog Calculation (via command Calc Grid on Grid menu)

In this case, the grid of the active variant or the grids of all variants or a selection of variants can be calculated.

Calculation Progress

With lasting grid calculations the following, estimated time intervals, estimated based on the calculation progress and the project size, are displayed on the progress dialog:

  • the elapsed time interval (format hh\:mm:ss) and
  • remaining time interval for the calculation (format hh\:mm:ss).

If no calculation area has been defined (see Selecting Data for the Calculation) the calculation is performed within the entire limits (see Options|Limits menu). Otherwise, only the active calculation areas will be calculated.

The grid calculation takes into account all objects and sound sources, even if they lie outside the specified calculation area (see also Check Consistency chapter Consistency Check).

Update duringGrid Calculation

With the activated option „Update during Grid Calculation“ (menu Options|Miscellaneous) the calculated grid is built up by colored areas while the calculation is still in progress.

Canceling/Interrupting the Grid Calculation

A grid calculation may be stopped, or interrupted to be resumed later on, at exactly the point where it was stopped. Click the „Stop“ button and wait until CadnaA has interrupted the calculation.

Resuming a Grid Calculation

In order to later relaunch a canceled grid calculation, first save the project file. CadnaA will save with this the progress status of the grid calculation. Select the command Grid|Calculate Grid. while holding the SHIFT key pressed to resume the grid calculation.
