I'm trying to solve a problem in the form:
D[T[x,t],t]==A*D[T[x,t],{x,2}]
with NDSolve
I have two boundary conditions:
T[0,t]==To AND D[T[x,t],x]==0 @ x==L
and one initial Value:
T[x,0]==Tinit
At (x,t)=(0,0) the boundary conditions conflict
so I set up an If statement to take care of this:
new Initial condition
If[x>0,(T[x,0]==Tinit),(T[0,0]==To)]
The problem is when I use NDSolve to solve this problem
It says that the equation list must contain an equation
and an initial condition
how do I get NDSolve to use the If statement?
I have tried setting up a series of functions of x
to no avail
