<br><span dir="ltr" style="margin-top:0px;margin-bottom:0px">You are likely correct if there is a pre compiled version of Fuka with spritz. If the data was generated with the latest release (since June 25), there is a discrepancy with how the numerical domains are constructed and stored as noted in the Readme. Linking against the latest library should resolve the ndim error.</span>
<br>
<br><span dir="ltr" style="margin-top:0px;margin-bottom:0px">Regarding your cfg, I believe you have to use brackets, not parentheses, e.g. ${HOME_KADATH}, for the etk config parser to recognize environment variables.</span>

<p>Hi Fatemeh,</p>
<p>The thorns you've disabled in the thornlist are responsible for the import of the data in the ADMBase / Hydrobase variables and interact directly with the FUKA exporters (in the bundled/separate FUKA installation). As such, they are necessary to import FUKA ID and simultaneously independent of the thorns you use for subsequent evolution.</p>
<p>The kadathimport thorn provides the headers for the import functions for specific initial data, whose implementation is then linked from libkadath.a. </p>
<p>I would recommend that you uncomment the thorns in the thornlist, recompile (kadath library linking is still governed by the .cfg file, which shouldn't change) and re-enable the thorns in the parameter file so that they're active and the ETK can schedule the import routines in the appropriate bins.</p>
<p>I was actually unaware that bnsanalysis and related analysis thorns depend on the kadath importer thorns. Is this a custom extension or is it possible that some other thorn lists them as depencencies? </p>
<p>In any case, doing the above should help.</p>
<p>Best regards</p>
<p>Konrad</p>
