i need your help plz i have an issue it show me error that you have fewer dependent variable than equation but i have 4 equation and 4 dependent variable sir please check it be the issue
Thank you sir what should i do now
Your equation bcs[Re1, \[Beta], A1, S1, S2][[1, 1]] is a little odd:
bcs[Re1, \[Beta], A1, S1, S2][[1, 1]]
u[t, x, 0] == Re1*x + Derivative[0, 0, 1][u][t, x, y] + Derivative[0, 1, 0][v][t, x, y]
The left-hand side has y==0 while the right-hand side has free y. Are you sure of that?
y==0
y
Dear Abid Hussain,
If you are asking me, "what should i do now," I would add to Gianluca's comment that you say in the original post (OP) that you have 4 equations in 4 unknowns. The code has 5 equations in 4 unknowns. I'd suggest that the code be changed to the 4 equations in 4 unknowns you refer to in the OP. I don't know what they are, so I cannot offer any further advice.
