Hello. I'm a third-year student of Moscow State University, mechanical and mathematical faculty. My coursework is connected with solving tasks of nonlinear theory of elasticity using Mathematica. Specifically, I study a theory of superimposed large deformations in plane elasticity. I wrote a program which calculates tensor of tensions at plane with elliptical hole, strained by forces at infinity. All calculations are symbolical (the answer is a function, depending on x and y). Because of huge formulas, long mechanical expressions, complex operations e.t.c my program is VERY slow. For example, to get satisfying results I must wait about half a day. But my task considers only one hole! And it must be developed to multihole cases. Now it's impossible. I have thought about that problem. The only way out, that I can see now, is to convert my program to C++. It's known that compilators are much faster than interpretators. But I don't know how to perform it. Is it possible? May be you can advise me other ways to speed up my program or know somebody who can answer this question. I'll send you my program, if you wish it. I'll be glad to hear any proposals. Thanks a lot. -- Best regards, Anatoly mailto:versh1984 at mail.ru
