Last week we finished preparing the Final Presentation that was due on Wednesday May 5, 1999.  Some final test cases were run and results were introduced during the presentation...these results will be further discussed in the final report due today at 5pm.  The midterm report editing and final report writing was completed.  The final report will be turned in today in the afternoon.

During this past week we concentrated in finishing up our respective test cases and scenarios so that they could be included in the final presentation.  A few test cases were run and visualized with Tecplot. Several movies were made and presented to Dr. Carey for evaluation.  We chose the more representative case to be introduced during this weeks presentation in the 5th of May.

Considerable progress was made by Gary and Alex on the MATLAB feasibility study case.  Only a simple case was studied and due to time constraints will be the only case presented in the final presentation and report.  The case is quite representative though and will be able to demonstrate how an optimization toolkit (MATLAB's in this case) would be useful to the design process of Fluid/heat systems.  I was visualizing the new test cases that were suggested by Dr. Carey.  We ran into code problems again and sat down with Bill and Dr. Carey to talk about them for quite some time.  We were able to solve the more pressing problems and get ahead in the test visualization and running of the final scenario that will be presented in the final report and presentation.

Last week while Dr. Carey was out of town I ran about 12 different cases and visualized them.  There were some problems in the choice of boundary conditions that was making the code blow up.  Due to the iterative process of the code's structure we were arriving and oscillating solutions that obviously do not happen in real life.  These code complications were solved giving more forgiving boundary conditions, such as slip walls and a mixed boundary condition on the top surface.  Gary should have been working on the MATLAB, not so much progress as of now, but diligently learning the different MATLAB toolboxes.

There were some disagreements between Gary and myself concerning communication.  These disagreements were solved with the mediation of Dr. Carey.  From now on Gary and I will work on the project separately and will get together to discuss each others work and for the preparation of the final presentation and report.  Gary will start on the design feasibility study using the optimization toolbox in Matlab at this time and I will continue with the running of the MGFLO code and the visualization of the results from test cases.

Last week was dedicated to finish preparing the MidTerm Presentation (during the beginning of the week) that was due on March 31st.  The remaining of the week was used to finish writing the MidTerm Report and it will be turned in tomorrow April 6th by 5pm.  Several advancements were done in the running of cases with the MGFLO code and these were included in the presentation and will be included in the upcoming report.

I looked up in a fluids/thermo book the different parameters for water and set up several test cases.  I am going to put these test cases aside to concentrate fully in the fictitious fluid cases that we are going to present on the midterm presentation and report.  Gary was supposed to go over the literature review that I did at the beginning of the semester and actually write down the names of the technical papers and articles and summarize the abstract of each of them.

 Going up the learning curve and now I can set up problems on my own.  I have ran about 16 different cases.  We are trying to fit a space-design region that might be able to give us more insight in the design of the fluid/thermal systems for our final presentation.  For the midterm presentation we will only present the test cases that have been run on fictitious fluids even though by then we might have started a few scenarios with water.  We need to find the parameters for water for next week.

The code was run in parallel processor mode.  I tested different cases on dual processor, eight processor and 16 processor mode.  Depending on the complexity of the problem dual processor was faster than 16 processor.  This is due to the amount of communication time that the processors need between each other.  If the problem is complex then 16 processor ran the problem much faster.  Visualization of the results were done with Tecplot and several more cases were suggested by Dr. Carey to be run in the next week.

This past week as usual we met at 1:30pm on Monday with Dr. Carey.
On Monday the midterm presentation was postponed for 2 weeks.  This
gives us more time to actually get some test cases run and identified.
This week was dedicated to library and web research.  We read several
technical papers, and wrote a short summary on important background
information.  Also a bibliography was put together for future
reference.  On Wednesday Bill Gary and Susan met to go over a test
scenario of the MGFLO code (I was sick and was not able to attend).
The code running was successful and TechPlot was used to quickly view
the validity of the results.  The code was run in single processor mode.
In the future the code will be run in parallel mode and interesting
results (evaluated through TechPlot) will be 3-D rendered on Ensight
for greater manageability of the results.

Last monday was the first monday we met.  The weekly meeting will be
held at 1:30PM in Dr. Carey's Office on the 3rd floor of WRW.
During this meeting we all discussed what the project direction was
going to be, and also what was expected from us.  This information was
formalized in an email that Dr. Carey sent out after the meeting. 
(Dr. Carey's email is available if needed).  On Wednesday we met with
Bill Barth to get my CFD account ready to run the MGFLO code that we 
are going to be working with.  There were some problems compiling the
code and the meeting was postponed until Friday at 1pm.  At that time
Susan Buck was also present.  We finally got the code to compile and we
reviewed the source code and input file.
During this monday's meeting we will discuss with Dr. Carey about what
preliminary test scenarios we should run (i.e. what fluid, what initial
conditions and what boundary conditions, etc.)

Last week I met with Dr. Carey.  I gave Dr. Carey our schedules so 
that we could find a time when we could all meet.  Dr. Carey gave me
some information on Fluids in microgravity as well as the physics of
fluid dynamics.  He also gave me technical papers on similar topics.
On wednesday we had our preliminary oral presentation.  The remaining
of the week we did some more web and library research.  
People that are going to be involved in this project from the CFD-LAB
are:
Bill Barth
Alex Ardelea
Susan Buck

Last week the microG project was finally formalized.  Due to Dr. Carey's
and my own illness this process has taken a little longer than expected.
Our contact has been through email.  I plan to meet with Dr. Carey this
week.  Dr. Carey was also out of town during this past week.  We
have done some web research and a little bit of library research.

Last week projects were assigned.  I was assigned to the CFD-LAB
funded project on microgravity (microG). Gary Cox and I will be 
working together in this project.  Dr. Carey will be the supervisor
of the project and several people in the CFD-LAB will be of assistance
also.
