<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying y to compare the result obtained by SimNIBS with that one calculated by FEniCS (<a href="https://fenicsproject.org/">https://fenicsproject.org/</a>) for a tDCS simulation. For this purpose, I have imported .msh file generated
by a SimNIBS simulation into FEniCS. I have used the spherical model provided in SimNIBS dataset. Now, I have two questions:<o:p></o:p></p>

<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]><span dir="LTR"></span>How can I get the electrical potentials of nodes and corresponding nodal coordinates? In earlier versions of SimNIBS, I used “v = fem.tdcs_getdp”. I was wondering if there is a similar command in SimNIBS 3.2.<o:p></o:p></p>
<p class="MsoListParagraph"><o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]><span dir="LTR"></span>About applying boundary condition, as I understood, SimNIBS uses a constant potential on electrodes (Say -1 on Cathode and 0 on Anode). After solving the FEM system of equations, then potentials are scaled to reach
the given current set for electrodes ( I mean we know the potential on 2101 and 1501 surfaces, both side of Anode, and we know the conductivity of the electrode, 29.4 S/m, then we can determine the current passing through the electrode). Am I right?<o:p></o:p></p>
