Dear Jorge,
That’s normal as you are multiplying your time domain function by an amplitude of 0 (Value).
It should be 1 or the actual amplitude of the current (time independent):
Constraint{
{ Name Source_jDensZ; Type Assign;
Case {{ Region Vol_source; Value 1;
TimeFunction jsz[]; }}
}
}
Best,
Ruth

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