I have not used non-Cartesian geometries in 3D with FLASH and generally they’re less supported/tested but in principle you should be able to use the “cylindrical” geometry. I think I read a paper on the Sedov problem recently that improved the 3D spherical MHD solver so that might be worth a look too.</div><div><br></div><div>Not sure regarding the current files. You may need to tweak a few routines.</div><div><br></div><div>Best,</div><div>Ryan<br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Jul 22, 2024, at 9:27 PM, lizy <3287940670@qq.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=GB18030"><p class="MsoNormal" style="line-height:150%"><span lang="EN-US" style="font-size:

disturb you amidst your busy schedule. I want to study the situation where
there are water droplets inside a cylindrical conductor. Water droplets may not
necessarily be on the axis of symmetry. Therefore, I will use 3D instead of
axisymmetric research.<o:p></o:p></span></p><p class="MsoNormal" style="line-height:150%"><span lang="EN-US" style="font-size:

establish the relationship between current and boundary magnetic field to make
the imported current file meaningful. Is the method of importing current files
suitable for 3D calculations? For example, the calculation area of a
three-dimensional cylinder or cube. Or is it only applicable to two-dimensional
axisymmetric conditions like in the case study?<o:p></o:p></span></p><p class="MsoNormal" style="text-indent:240.0pt;mso-char-indent-count:24.0;
