Hi,

you did not try to enter the two lines above, did you?

The first one would make sense if it would read

Derivative[0,1][v][t,0]==0

I guess you know about the meaning, because you're asking for BCs.

But I can't imagine how

v(0,1)[t,0]==0

should make sense without an extension of Mathematica's parser.
