Suppose your CFD code can handle nonelementary blocks. Combine as many blocks of Fig. as you can. The only restriction is that in any one block, the number of i-intervals and the number of j-intervals must be constants. Show that you can create a structured grid with only three nonelementary blocks. Renumber all the blocks and indicate how many i- and j-intervals are contained in each block. Add up all the cells and verify that the total number of cells does not change.

- We have designed a divide-and-conquer algorithm that runs on an input of size n. This algorithm works by spending O(1) time splitting the problem in half, then does a recursive call on each half, then spends O(n2 ) time combining the solutions to the recursive calls. On small inputs, the algorithm takes a constant amount of time. We want to see how long this algorithm takes, in terms of n to perform the task. (a) First, write a recurrence relation that corresponds to the time-complexity of the above divide and conquer algorithm. (b) Then, solve the relation to come with the worst-case time taken for the algorithm.

I tried making my own function and using the MATLAB function, but the result is matrices that are not equal to each other. But, if I were to use the 'ZYX' sequence, I would get a matrix that is equal to the transpose of the matrix produced by my function.I mean that transpose(EA123toDCM) = E123toDCM if I changed the sequence to 'ZYX'. I never got two equal matrices. Can you fix my code so I would get two equal DCM matrices for the body 1-2-3 sequence? Also, for the E123toDCM line, I am using the sequence 'XYZ'. Is that correct or should it be 'ZYX'? I know that that for a DCM of sequence 1-2-3 = R3(theta1)*R2(theta2)*R1(theta3). Is ZYX sequence the same as a 1-2-3 sequence?

Copy the file into your working directory and use it as any other Matlab .m file or build-in intrinsic Matlab function (just call it using its name process). The only difference between a .p and a .m file is that the source code of the .p file is not visible. Find all roots of g(x) in the interval 0 ≤ x ≤ 10 to a tolerance in function of at least 10-10 using mySecant from problem 2. Recall that any .m or .p function file can be passed as an argument into another function by prefacing the function name by a @, e.g., @process can be passed as an argument into any Matlab function that uses a function as an input argument, for example fplot(@process,...) for plotting a function.

- Hi, I need help on this question:a) Choose boundary conditions (b.c.) for the boundaries A-G from the types of b.c. typically implemented with an incompressible CFD solver. State what quantities those b.c. impose, and which they leave undefined. Justify your choice of boundary condition. b) Discuss the most important errors your choice of b.c. may introduce and how those could be remedied. c) While walking past your desk, your team-leader reminds you that the quantity of interest is the massflow in the lower channel, and proposes to use a slip-wall condition for B. Unfortunately she doesn’t explain her reasoning. For the next team meeting, prepare a discussion of the pros and cons of that suggestion, and explain whether or not you think this suggestion should be followed.arrow_forwardCommand: PLOTTERMANAGER (from the autocad file m TO CONFIGURE A LOCAL, NONSYSTEM PLOTTER 10.
