Dear Jorge,
<div class=""><br class="">
</div>
<div class="">That’s normal as you are multiplying your time domain function by an amplitude of 0 (Value).</div>
<div class="">It should be 1 or the actual amplitude of the current (time independent):</div>

<div class="">Dear all,<br class="">
<br class="">
I want to have a ramp-up source current,<br class="">
<br class="">
I have defined it like this in the function block:<br class="">
<br class="">
Funcion{<br class="">
jsz[Coils]=-numberCoils*currentMax/SurfaceArea[]* $Time / timeMax;<br class="">
}<br class="">
<br class="">
and I set it as a constraint<br class="">
<br class="">
Constraint{<br class="">
{ Name Source_jDensZ; Type Assign;<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>Case {{ Region Vol_source; Value 0;<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span><span class="Apple-tab-span" style="white-space:pre"></span>TimeFunction jsz[]; }}<br class="">
}<br class="">
}<br class="">
<br class="">
However, this constraint is not updated and the current seem to be 0 for all iterations of the time loop in the resolution block,<br class="">
<br class="">
Resolution{<br class="">
{ Name AA;<br class="">
System {<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>{ Name A; NameOfFormulation AMagneto; }<br class="">
}<br class="">
Operation {<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>InitSolution[A];<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>PostOperation[B];<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>TimeLoopTheta[timeO, timeMax, deltaTime, 1]{<br class="">
//<span class="Apple-tab-span" style="white-space:pre"> </span><span class="Apple-tab-span" style="white-space:pre"></span>UpdateConstraint[ A, Coils, Assign ]; // this line does nothing :(<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span><span class="Apple-tab-span" style="white-space:pre"></span>Generate[A]; Solve[A];<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span><span class="Apple-tab-span" style="white-space:pre"></span>SaveSolution[A];<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span><span class="Apple-tab-span" style="white-space:pre"></span>PostOperation[B];<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>}<br class="">
}<br class="">
}<br class="">
}<br class="">
<br class="">
<br class="">
I am guessing the problem is in the parameter $Time that I use to define the time function... but I do not know how the<br class="">
proper way of using it is nor if there is a work around to do what I am trying do<br class="">
<br class="">
Some help would be greatly appreciated,<br class="">
Thanks a lot in advance,<br class="">
<br class="">
All the best,<br class="">
Jorge<br class="">
