    FORTRAN &amp; VISUAL STUDIO -- Can Digital F work in VS6 or higher?

    Sorry, I ceased using Fortran on win months ago... Now I'm using Intel Fortran Compiler for Linux, that is free for non commercial purposes... I thought it was the same for the windows version. Sorry, my fault __________________________________________ Everything should be made as easy as...

    Effect of a bar in air flow

    By the way, modeling the shape of the bar as a symmetric airfoil makes the drag 10 times lower, with an obvious effect over the lenght and the thickness of the wake. Since the bar has a diameter of 20 mm, even in the case of a turbulent flow, its effects would be practically negligible...

    Effect of a bar in air flow

    Well, you need more data to find a solution. In particular, you need the viscosity of the fluid and the temperature, i.e. you need to calculate the Reynolds number of your flow. The Reynolds number defines the ratio between inertial forces and viscous forces of the flow. In general, if the...

    FORTRAN &amp; VISUAL STUDIO -- Can Digital F work in VS6 or higher?

    You can download the Intel Fortran Compiler from the intel homesite (it's free for non-commercial purposes). Install MS Visual Studio first, then install the intel fortran compiler. During the installation it will recognize Visual Studio and it will embed its features in it. After that, you will...

    Intel Visual Fortran: Change icon for console applications

    Hi there, this is my question: Assuming that I already have an .ICO file, how do I change the program icon for a console application? __________________________________________ Everything should be made as easy as possible, but not easier Albert Einstein

    DISLIN graphics library

    Hi there, has anyone of you installed the Dislin graphics library (available here) for Intel Fortran Compiler? I try to install it using the references on the site (setting the PATH directory etc), but it still doesn't work, and the compiler can't find it. Can anyone explain me how to do, or...

    zero lift and induced drag

    You may check in literature for the "D'Alembert Paradox". For an unviscid flow, you will obtain zero drag for a zero lift finite wing. Everything should be made as easy as possible, but not easier Albert Einstein

    Can 35% H2O2 be used in rocket engines?

    H2O2 in low percentage is not hypergolic. Furthermore, it is extremely difficult to ignite, and to obtain a stable combustion from it Everything should be made as easy as possible, but not easier Albert Einstein

    Tolerancing

    Strictly speaking, The dia you've measured is out of tolerance. But you should control which is the error tolerance of your measurement machine; say, if it measure with a precision of .0001" or less. That could make your measure re-enter in the tolerance required Everything should be made as...

    Aerothermoelastic Analisys of a FGM wing

    I'm going to analyze the aerothermoelastic behaviour of a wing made of Functionally Gradient Material (FGM). Does anyone already done such a thing? Could you give some tips, or tell me where to find some articles?
