Hello everyone,
I am a new comsol user, recently I have meet a problem and don't know how to solve it.
The equation are as follow:

X=0, when V<0.5;
d(X,t)=V,when V>=0.5;
V=sin(2*pi*t);

I don't know how to solve these equations using comsol, can anyone give me some sugesstions?
Thank you for your reading my posts and I am looking forward to reply.
