Never mind, I found your entries on nanohub

Hello Marvin, it appears that the patent link is broken. Also, MCNP is generally free depending on your status (student, post doc, professor). You will have to fill out the proper documentation from Los Alamos National Laboratory.

I've been having difficulty in successfully compiling the MCNP executable with the MPI/MPICH libraries on Scientific Linux 6.x (whatever the latest version is). I'm currently using MCNP5, and the latest distribution DVD. The compiler is GCC, and the MPI is MPICH 1.4.x (the version immediately...

Thank you both, I greatly appreciate the clarity. I apologize that it took so long for me to reply.

Could anyone provide a concise explanation of the function of a discriminator in what is basically a, Detector => Pre-Amp => Amp => Discriminator => MCA (Multi-Channel Analyzer), circuit. I have a basic knowledge of electronics, but I'm still new to this. Thank you!

I'm having some difficulty figuring out exactly what the issue is here. The compiler tells me that I'm lacking types for certain function variables, but when I define them in the module it tells me they are defined in multiple locations, and still won't compile. what can I do to absolve this...

Thank you! I figured out where the error was, in passing the variables, but after reading that I was reaffirmed on what I thought the program should be doing.

Alright, I have a situation where I need to create a user defined function (I've done that) next I need to write a subroutine that uses the bisection method to find the zeros of said function (I've also done that) but I can't figure out how to call on the user defined function to evaluate at...

Well, it is a .edu site... I really think it should, I mean, this paper isn't even for a science course, it's technical writing for engineers. The only way I could bear through the paper was to write about a topic that I really enjoy! Though I am interested in finding a textbook source for this.

The efficiency to which I am referring is the amount of mass converted to energy. I need to find an academic source to cite that fusion is more efficient in this respect than fission. Any sources?

I apologize for my lack of formatting, I'm not particularly skilled yet at using the formatting statements in Fortran, it's even worse in the main code with all the write statements that had to be added. I definitely should have specified that the variables are initialized from input by the...

All the variables have been initialized, I'm sorry I forgot to include the code for the module that declares some of the variables that the main program and my subroutines use. This code compiles fine (when used with the main program of course) but the results it produces are off by some strange...

Alright, I cannot seem to get this subroutine to return the correct sums for the trapezoidal rule... Where do I need to fix? SUBROUTINE atrap(i) USE space_data IMPLICIT NONE INTEGER :: i, j REAL :: f_b1, f_b2, f_x1, f_x2, trap_area REAL :: delta_x trap_area = 0 f_b1 = lower f_b2...

I really appreciate all the help guys! I actually wound up debugging it during class. I discovered that I can reference the function in my case statements, where all 3 of the data inputs can be used in the arguments and computations. The TA's were amazed that it worked... Now I have a...

I've written it as one function now, but after making a choice selection it tells me I'm missing a left parenthesis in format. program calculator IMPLICIT NONE REAL :: addition, subtraction, multiplication, division, x, y, j, k, x_data, y_data !x = A, y = B CHARACTER :: choice, a, b, c, d...
