4. Analyze static electrostatic phenomena using computer-aided analysis Analysis

tools
5. Compare results from analytical, empirical, and simulation-based Analysis
investigations, and explain differences in results, due to the strengths and
weaknesses of the different approaches
2. ACTIVITY DETAILS (ESTIMATED 10-12 HOURS)
STEP 1 – MASTERING THE MECHANICS (Estimated 4-6 hours)
Go through Chapters 3, 4, 5 and 6 and the following worked problems in the Edminister
(2014):
Chapter 3 (13 worked examples)
3.1, 3.2, 3.4, 3.7, 3.8, 3.9, 3.11, 3.12, 3.14, 3.15, 3.16, 3.20, 3.21.
4.1, 4.2, 4.3, 4.4, 4.6, 4.8, 4.9, 4.11, 4.12, 4.15, 4.17.
5.2, 5.3, 5.4, 5.7, 5.9, 5.11, 5.12, 5.15, 5.16, 5.17, 5.20, 5.22, 5.23.
5.1, 5.3, 5.5, 5.7, 5.8, 5.9, 5.12, 5.13, 5.15, 5.17.
STEP 2 – TESTING YOUR UNDERSTANDING (Estimated 1.5 hours)
Complete Quiz: Electrostatics1 on the course website. It is not worth marks, but it will help
you to test your understanding and help me to see where there may be gaps. You can repeat
the questions as many times as you like. Please note that STEP 2 serves as a check that you
can extend the learnings of the worked examples to other situations. You can review the
2
solutions for these questions. You are encouraged to work with your peers to collaboratively
ensure that you master the concepts covered. This would also serve as your budgeted tutorial
hour for this week, so there would be no face to face tutorial sessions. If there are any
questions please post on the Course Forum.
STEP 3 – CONCEPT SCAFFOLDING (Estimated 1.5 hours)
You will be presented with several concepts via the Course Forum, relating to the material
covered in the previous steps. We will have open-ended discussions of these in an attempt to
reinforce your understanding of key concepts. This stage is crucial to the following stages, so
please attempt to interact with each other as much as possible. The TA and I would moderate
the discussions, and provide responses primarily when such interventions are needed.
STEP 4 – BROADENING YOUR PERPECTIVE (Estimated 1 hour)
The first half of class, week 2, Wednesday will be devoted to open discussions about different
perspectives on key content. This would serve to reinforce the work you have done to date,
and also to discuss various advanced topics relating to the material covered in Step 1. Please
make every effort to attend class and participate.
STEP 5 – APPLICATION OF THEORY TO TOY EXAMPLES (Estimated 2 hours)
For the 2nd half of class on Wednesday, you would be provided with a case study. This would
be uploaded to the site following class on Monday (Week 2). You would be required to go
through the document and discuss the material to get a sense of how you would proceed with
the problem presented. You would be required to do both analytical (pen and paper) as well
as Matlab +PDE Toolkit activities. Your approaches would be discussed in class, and a
nominal solution guide would be presented.
You would be required to go through the solution guide as a self or group-study exercise and
compare your responses to those provided. It is anticipated that this post-class activity should
not exceed 1 hour.
3
Since these case studies would be of comparable difficulty to the exam-level questions, you
are encouraged to participate. In addition to assisting with the in-course exam the skills
developed here would be useful in your group project.
3. PROPOSED ACTIVITY SCHEDULE

• Before end of Tuesday, Course Week 2 (week of 27th January):
o complete STEP 1 - Edminister (2014), Chapters 3, 4, 5 & 6 worked examples; and
o complete STEP 2.
• Wednesday, Course Week 2 (week of 27th January):

4. POST-ACTIVITY DETAILS (WEEK 3)

In Week 3 during the Monday (28/1/2019) class, we will have a short feedback session to get
a sense of your general comfort with the material. There will be a 15-minute review of your
achievement of the learning outcomes of this exercise, whereby you are free to ask any
questions that you may have on the topics presented and their applications, or request
feedback on your work in this activity.
