Question

Can this PDE be solvable with Machcad?

I am struggling with a heat equation which has very complec heat generation term.

In the attachment, T is temperature, x,y,x are axes perpendicular to each other, t is time, and other parameters are assumed to be known.

Here, what I want to ask is

1) Is this PDE solvable with Mathcad (w.r.t case 1 and case 2)

or do I have to other softwares like c++, matlab

2) If so, is there anybody who is willing to teach me the code?

I would appreciate it if anybody give me an answer.

Thank you.

I would not say immediately that it's not solvable using Mathcad.

But please provide a Mathcad worksheet to prevent mistakes in erroneously interpreting your handwriting.

Also, while I know the divergence operator, I'm unsure how to interpret it squared. Would that mean you want to solve:

or:

?

And finally the last term between the brackets of the q(x,t) function, I cannot make anything of it.

Del squared is the Laplacian, and your second form is correct.

Thanks Rich, just found that out.

Now we need two boundary conditions for the first case...
