$PDE := {diff(C(x, t), t)+lambda[3]*(diff(C(x, t), t, t))-(diff(C(x, t), x, x))/Sc-Sr*(diff(theta(x, t), x, x))-Sr*lambda[3]*(diff(C(x, t), t, x, x)) = 0, diff(theta(x, t), t)+lambda[2]*(diff(theta(x, t), t, t))-(diff(theta(x, t), x, x))/Pr-Du*(diff(C(x, t), x, x))-Du*(diff(C(x, t), t, x, x))*lambda[2] = 0, diff(u(x, t), t)+lambda[1]*(diff(u(x, t), t, t))-(diff(u(x, t), x, x))+Ha^2*u(x, t)+lambda[1]*Ha^2*(diff(u(x, t), t))-Gr*theta(x, t)-lambda[1]*Gr*(diff(theta(x, t), t)) = 0}:$

IBC := {C(0, t) = 1+d(1-cos(varpi*t)), C(1, t) = 1, C(x, 0) = 0, theta(0, t) = 1+b(1-cos(varpi*t)), theta(1, t) = 1, theta(x, 0) = 0, u(0, t) = 1-cos(varpi*t), u(1, t) = 1, u(x, 0) = 0, (D[2](C))(x, 0) = 0, (D[2](theta))(x, 0) = 0, (D[2](u))(x, 0) = 0}:

Error, (in pdsolve/numeric/plot) unable to compute solution for t>INFO["failtime"]:
unable to store 1+d(.00124973960503372) when datatype=float[8]

Error, (in plots:-display) expecting plot structures but received: {p11, p21}
