I am looking for a numerical solver for a parabolic PDE (up to 2nd order derivatives but no mixed ones) on the spatio-temporal domain [X x Y x T], either as an external package or as MAPLE code.  

I have coded the method of lines on the domain [X x T] and indeed also used pdsolve as a check for that case. However, pdsolve (numerical) cannot solve the PDEs on the domain [X x Y x T].  The run times and memory requirements for the latter case would of course be significantly greater.  

I am about to code up the method of lines (in MAPLE) on the domain [X x Y x T], but am wondering whether there exist external FORTRAN or C code packages that would be faster if called up in MAPLE and whose results would then be post-pocessed in MAPLE.

Does anyone have any suggestions?

How I can graph parabolic cylinder y=x^2 and elipsoid x^2+4y^2+4z^2=16 on a three-dimensional coordinate system?

Dear all,

I tried to use pdsolve to solve the parabolic pde but get the unexpected answer:

Is it the PDESolStruc or the other structure? Where can I find the description about this kind of structure.

Thanks.

This excellent application www.maplesoft.com/applications/view.aspx?SID=5523&view

demonstrates the paths of light rays against various surfaces.  Can the initialization code be made more efficient and faster?  The only thing I could think of was to remove the call to plottools and replace it with just plot and adding an extra...
