Known problems with LASAT

Problem 2026-01-14
Applies to Lopzet with nested grids

Titel

No modification of the set of nested grids with option -f
Description

Lopzet reads the grid information from file grid.def and then attempts to read the concentration files for all these grids and the concentration value from the finest grid containing the monitor point. This mechanism may not be bypassed by specifying the name format (option -f).

When using this option, it is important that the placeholders for the grid indices (and the time intervals) are retained in the format specification (as in the standard setting), for example -fcon%04da%d%d.dmna. Otherwise, Lopzet will become confused and assigns the grid indices for the monitor points incorrectly.

Workaround Note this information.

Description

The optional comment that can be specified for the output file must not contain a comma, otherwise AddIm will get confused when counting the comma-separated parameters.

Workaround Don't use a comma.

LTool DefCheck with meteo.def without time series

If no time series is defined in meteo.def, the LASAT tool DefCheck hangs on checking the project.
