Solved in Matlab using the mesh geometry (2D or 3D) some physical three-dimensional problem.
At the exit to the graphical construction solutions: line temperature isotherms in the (O-graphs) can be represented as a 2D (slices, ie a fiber breakdown for Z axis with an interval), and preferably in 3D color (3d not necessarily but advised).
At the entrance of a number of formulas and a table with the values of the coefficients, which depend on the coordinates and time (for the first time izmenyayuschiesyavo time coefficients can be constants).
Performance time-hot task, the faster, the better
money - pay as agreed.
Waiting for feedback and suggestions.
