Hi everyone, here we are again with more serius issues this time.

I have a system of DE to solve. My system is made of coupled 3 PDE`s with 1 ODE. My problem is that the computation is aborted due failure at memory allocation, here is the message:

"Error, (in factor/nexteval) Cannot Allocate Memory (size=151060480)"

I`ve checked the kernelopts about datalimit and its already infinity. My computer is a Turion x2 with 4Gb of Ram (system...

Hi everyone.

I have been experiencing a problem trying to solve a coupled system of 4 differencial equations, 2 PDEs with 2 ODE.

My problem is that a got a message back as I try to solve the system:

"Error, (in pdsolve/numeric/process_IBCs) improper op or subscript selector"

My first question is: Am I defining the IBCs rightly?

If not, I don`t have a clue on how to solve this problem, I really apreciate some help out here.
