mathematica 求解偏微分方程组的问题，求解没有反应

func1 = {D[u[x, y], {x, 2}] + \[Mu]*D[v[x, y], {x}, {y}] - \[Beta]^2*
u[x, y] == 0,
D[v[x, y], {y, 2}] + \[Mu]*D[u[x, y], {x}, {y}] - \[Beta]^2*
v[x, y] == 0}
cons = {u[0, y] == 0, v[x, 0] == 0,
D[u[0, y], {y}] + D[v[0, y], {x}] == 0,
D[u[x, 0], {y}] + D[v[x, 0], {x}] ==
0，D[u[L/2, y], {x}] + \[Mu]*
D[v[L/2, y], {y}] - (1 + \[Mu])*\[Alpha]*T == 0,
D[v[x, B/2], {y}] + \[Mu]*D[u[x, B/2], {x}] - (1 + \[Mu])*\[Alpha]*
T == 0}
DSolveValue[{func1, cons}, {u[x, y], v[x, y]}, {x, y}]
求解之后没有反应，中间有一部分的边界条件没有显示

输出的红框部分与我的代码不一样，不知道为什么
