Spring 2009 Mid-Semester Contributions
I am a member of the Design team. I have spent the semester becoming familiar with the design files, and updating the sedimentation tank inlet manifold program. In this program, I redefined the width of the inlet manifold to be a function of the width of a sedimentation tank, the width of the sludge drain, and the thickness of the slope plate. I went through all of the other files to update the functions that used half of the width of the sedimentation tank when in actuality the width of the inlet slope was needed. I also edited the function that calculated the maximum possible length of a sedimentation tank, and then added a check that the calculated length of the sedimentation tank does not exceed the maximum length. I have also started updating the variable naming guide to reflect the new and edited variables in the inlet manifold program. I added the hopper program to the Gracias design file, and I added a function within this program to determine the offset distance from the inlet channel that the top of the hopper needs to be. I also moved input variables into the input variables page instead of them being at the top of the program for which they are used. I have updated the Cuatro Communidades page to now have the correct dimensions that have been used in the plant. Overall, I have spent a lot of time debugging and checking to make sure that changed variable names were changed in all programs so that everything was correct and consistent.
Spring 2009 End of the Semester Contributions
Since the midterm, I have been mainly working on debugging the AutoCAD programs so that the Design Tool could come online. The focus of this task was to automate the drawing of the sedimentation tank. I was responsible for writing the code to draw and insert the inlet manifold slopes as well as the frame ledge for the lamella. Note: these AutoCAD pages need to be updated this Summer
During this process, the need for various MathCAD scripts that correspond to AutoCAD commands arose. I added several new functions in the MtoATranslators program that did this.
I also organized the hierarchy of the MathCAD programs so that now it is easy to debug single programs. It is only necessary to reference the MasterProgram, which now references all of the other programs. This step was necessary in order to prevent over referencing in other programs and slowing down the time it takes to load a program.
I was also responsible for keeping the sheets at the bottom of the Variable Naming Guide up to date so that they correctly displayed the inputs and outputs of each program.
On the wiki, I updated the pages for the inlet channel and exit channel, as well as the user inputs.
This last part of the semester, I have spent mostly testing different plant sizes and various sedimentation tanks, and then debugging as issues arise. Because the sedimentation tanks can now have variations of single or multiple tanks and/or bays, I have been working on how to array different combinations of sedimentation tanks so that the plants may scale up or down depending on the flow rate.
