<p class="MsoNormal" style="margin-bottom:6.0pt"><span lang="EN-GB">I am using an H-Phi magnetodynamic model and I would like to control the field on the outer boundaries of the modelling domain to match a specific time-dependant profile. Because the external
field I want to apply is too complex for the usual <i>Assign</i> type of constraint (it is the sum of two functions with different time dependences), I have been trying to use
<i>AssignFromResolution</i>. My current model (not working) is attached with this email. The issue is, during pre-processing, I get the following warning about the system for the pre-resolution, with is apparently empty :<o:p></o:p></span></p>
