Guidelines for CFD work and reports

Here are some suggestions for what a report using computational fluid dynamics (CFD) should include:
A.    Describe the problem in prose.
B.    This is a checklist of items to be written down:

  1. Equations solved, and values of any parameters in the equations;
  2. Geometry, including dimensions;
  3. Boundary conditions on all boundaries, including any parameter values;
  4. Mesh information, at first the number of elements and degrees of freedom, and the final report should include at least one plot of the mesh.

C.    Examine your results carefully.

  1. Plot lots of things;
  2. Look for oscillations (bad) and funny things;
  3. Do hand calculations of a simple case using standard formulas;
  4. Do at least some mesh refinement.

D.    Present results in tables, contour and surface plots, and line plots.
E.    What have you learned? Recommendations for improved solutions or new information.

One Response to Guidelines for CFD work and reports

  1. Many thanks for these hints…
    I am having problem with mesh refinement which is which parameter to choose in order to check the solution conversion. Can I use surface average value i.e. Re #?
    My case study is unsteady laminar flow in microchannels using COMSOL in a 2D.
    Any hint or literature referring on this issue will be very appropriated.
    Thanks again.
