Debugging BASEMENT

Since its early development, BASEMENT has become a robust an reliable tool for the numerically modelling of rivers. Yet there are a few little challenges and this page provides some answers (under development).

Import of XDMF Model Output Fails¶

XDMF error of wrong versions¶

Depending on the system environment, the header of results.xmdf may not be readable for QGIS. The two below tabs show the wrong and correct header lines. To fix the issue, open results.xmdf in a text editor (e.g., Notepad++ on Windows), replace the wrong with the correct header, and save the corrected results.xmdf.

<?xml version="1.0"?>
<Xdmf Version="3.0">

<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf Version="2.0">

XDMF error of wrong simulation directories¶

The results.xdmf contains geospatially explicit data (e.g., of flow velocity and water depth), which can be theoretically directly imported in QGIS with the Crayfish plugin (read more in the BASEMENT post-processing section). However, there is a little issue: QGIS may crash because of an invalid directory. To fix it:

1. Open results.xdmf in a text editor (e.g., Notepad++ on Windows).

2. Use the find-and-replace tool (CTRL + H keys in Notepad++) to remove file paths before results_aux.h5.

   • Search the results_aux.h5 string and identify the path written in front of it (e.g., C:\temp\).

   • Find and replace that user path, for example: Find = C:\temp\results_aux.h5 and Replace with = results_aux.h5.

3. After having removed all path occurrences in the document, save and close results.xdmf.

This issue is also discussed in the BASEMENT User Forum).
