Opening executable
- Check the number of available screens on computer. If displaying on a projection, the model may be opening on a separate screen. This can be checked by searching the Applications list in Windows Task Manager for the CLiDE executable running.
Opening XML file
- If the XML file has been edited using a text editor, an item within the XML may have been renamed. Save a new XML under a different name and compare the name of each variable to the XML that is needed. Update differing variable names.
- An XML saved in an older version of CLiDE may not work with newer versions and vice versa due to a different list of variables required in the XML file. Save a new XML under a different name and compare the name of each variable to the XML that is needed. Update differing variable names.
Loading initialisation data
- Check that the size of each array matches the other arrays and the header information.
- Check date information in Setup tab is as expected.
- Use a different text editor to view input files (line returns are picked up by some and not others). Notepad++ is recommended.
Simulation freezes
- Allow the simulation time to process large amounts of data. When processing a catchment with a large number of nodes the daily timestep may take a few minutes to complete.
- Increase the amount of memory available to the program by reducing the memory limit in the Setup tab to 1.
- Check groundwater input file for zero, negative or small values (<10 m). If the groundwater reaches zero during the simulation this can cause instability. To prevent this, the entire catchment can be uplifted by adding 50 m to each nodal elevation in the DEM, bedrock and initial groundwater files. This can be removed during post-processing if required.
- Check rainfall and potential evapotranspiration data exist for the previous, current and proceeding timestep being simulated when the platform froze.
- Ensure output from previous simulation is not open in another program, as output files can not be over-written (as an exception, some text editors will allow this).
No output is produced
- Check the save file time in the Setup tab is as expected (a value of 1440 is daily).
- Check options are checked in the Save Options bar at the top of the GUI.
- Check you are in the CLiDE.
