Hi Jose,<div><br></div><div>I&#39;m not sure if this is the cause of your MPI errors, but the m_mode and l_mode parameters in WeylScal4 are deprecated. You should instead use the l_max parameter, e.g.</div><div><br></div><div>

ActiveThorns = &quot;WeylScal4 Multipole&quot;</div><div>WeylScal4::offset                    = 1e-8</div><div>WeylScal4::fd_order                  = &quot;4th&quot;</div><div>WeylScal4::verbose                   = 0</div>

<div><br></div><div>Multipole::nradii = 8</div><div>Multipole::out_every = 128</div><div>Multipole::radius[0] = 15</div><div>Multipole::radius[1] = 30</div><div>Multipole::radius[2] = 40</div><div>Multipole::radius[3] = 50</div>

<div><br></div><div>Does somebody have probably a hint what is the best parameter setting? I am using following:</div><div><br></div><div>ActiveThorns = &quot;WeylScal4 Multipole&quot;</div><div>WeylScal4::offset                    = 1e-8</div>
