I used the following code and got the error:
Code (Text):

Error, (in pdsolve) invalid input: pdsolve/numeric expects its 2nd argument, IBCs, to be of type {list, set}, but received IBC

the code is:

how to amend this error?

Btw, the second boundary condition v_x(1,t) should be approximated by the equation $v(1,t)=1-0.000065\cdot \int_0^t \theta_3(\tau)y^4(t-\tau)d\tau$ by Forward Euler method, though I am not sure how to do this in maple.

Any tips are good for me, thanks.
P.S
$\theta_3$ is Jacobi theta_3 function.
I know that in maple there's this function in the software.
