Final Project Grading Procedure

Below are the grading segments. Yes, they add up to more than 100%; you do not have to have everything perfect to deserve full credit. The maximum credit given is 100%, in any case.

Correct program results 50%

The program must do what it is supposed to do.

If correct results have not been obtained, grading stops here, since obviously the first thing a program should do is produce the right results. Having a neat program or output is useless if the results are missing or wrong. The student should have spend the effort instead on fixing the problem(s).

Meet standard program requirements 15%

This section will be zero if any of the following is not achieved:

• Use of input file instead of recompilation to change values.
• No order increases in storage or work.
• Structured along the lines commonly used to compute multidimensional flows, i.e. does not abuse the fact that the given problems are small.
• No output-driven program logic. Output is an add-on.
• No work-arounds for lack of programming skills. (Example: running the program once for each output time.)
• Array dimensions explicitly specified at the start.

Program neatness 15%

This section will be zero if more than one of the following are not achieved:

• Use of blank lines to group related quantities together.
• Logically indented.
• No lines exceeding 72 characters.
• Logical break points, indented properly.
• No typos.
• Functions in separate files.
• No giving the instructor his own files back.
• Well designed graphs.
• Check inputs for validity.
• Statement numbers in order (Fortran).

The opinion of the instructor determines where the limit is. (Note: often items that reduce neatness also reduce readability)

Readability 15%

Factors:

• Program summary comment header that allows the program to be easily understood without having the formulae.
• Immediately understandable variable names.
• Variable names are identical to ones used in class wherever possible.
• No needless variables.
• Sufficient comments.
• Clear comments.
• No useless comments.
• Use of functions enhances readability instead of detracts from it.
• Variables grouped together to increase readability.
• Uses capabilities of the language to increase clarity.
• Uses statement numbers to end do loops in Fortran.

The final criteria are:

• the instructor can immediately understand what the program is doing without searching around in other parts of the program;
• the instructor feels he could still easily understand the program without having seen the formulae.

(Note: often items that reduce readability also reduce neatness).

Presentation of results 10%

This section will be zero if more than one of the following are not achieved:

• Readable, complete yet concise, discussion in good English.
• Every digit presented is of enough meaning to justify its reading, in the opinion of the instructor.
• The info is presented in the easiest to judge form (using graphics, statistical parameters, etcetera, where appropriate.)
• Some concise, meaningful, output during the computation to indicate how the program is doing.
• Sufficient results to determine what program did.

The opinion of the instructor determines where the limit is.

Analysis of results 10%

This section will be zero if more than one of the following are not achieved:

• Valid assertions.
• Comparison with available data.
• Demonstration of mesh convergence.
• Demonstration of asymptotic convergence.
• Discussion of the entropy layer.

The opinion of the instructor determines where the limit is.

Grading Procedure

• Skim through submitted pages.
• Check results. If incorrect, skim through program and assign 0-50% total grade based on the parts of the program that are clearly and easily seen to be correct.
• Read program header
• See whether declarations, input, initialization, main loop, and output sections are easy to locate.
• Read random segment in the declarations section.
• Read random segment in the input section.
• Read random segment in the initialization section.
• Read random part of the main loop.
• Look at output file.
• Read attached description.
• Mark grade sheet.
