<p>I am trying to solve a Poisson equation with <code>CT_MultiLevel</code> but without including <code>CT_Analytic</code> (which is advertised as an helper thorn). I found that this cannot be done because <code>CT_MultiLevel</code> explicitly calls the restriction operations on grid functions defined in <code>CT_Analytic</code>. For example, in <code>CT_RelaxError.cc</code>:</p>
<div class="codehilite"><pre><span></span><span> CT_Restrict(CCTK_PASS_CTOC, "CT_MultiLevel::psi"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_MultiLevel::coeffs"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testK"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testdxK"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testdyK"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testdzK"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testc1"); </span>
<span> CT_Restrict(CCTK_PASS_CTOC, "CT_Analytic::CT_testc2");</span>
</pre></div>
<p>If you don’t have <code>CT_Analytic</code> as an active thorn, the run will abort. (Are these restrictions needed?)</p>
