Homework Statement
I have a matrix A \in R^{m x m} where m = n^{2} and n = 2^{k} +1, k= 0,...,L.
As in the image attached,the original numbering in the case k=1 is [ 1 2 3 4 5 6 7 8 9], i want the nodes to be renumbered
to a new numbering T=[2 4 5 6 8 1 3 7 9] (meaning position 2 in...
Homework Statement
I have a designed a Finite Element code for a Poisson problem using
Bilinear Element.
- \DeltaU= 2\pi^{2}Sin(\pi X)Sin(\pi Y)
U = 0
The exact solution is given by : UEX = Sin(\pi X)Sin(\pi Y).
2. The attempt at a solution
On convergence analysis:Theoretically, if...
Dear Sir,
Thank you so much for your assistance.For two months,i've struggled with this.It forms 20% of my thesis work.Seeing the results has given me good health.
Thank You.
The nodes are colored BLUE and edges red,green,...Each element consist of the four nodes in that box. eg A(1) = {1 2 5 6},A(2) = {3 4 7 8}.The final solution is made of nodes in an element and and nodes (usually 2nodes) from neighbouring elements which share a common edge(straight line) eg for...
Homework Statement
Given a square grid ( n-by-n) with numbering 1:4n2 from the figure attached
(eg. n=2), the matrix: A = [1 2 5 6; 3 4 7 8;9 10 13 14;11 12 15 16] which corresponds
to the elements,ie row 1 corresponds to element 1,etc. is generated.i
want to create a new matrix such...
[b] I have a mesh (2-by-2) which is numbered 1:16.[b]

A = [1 2 5 6; 3 4 7 8;9 10 13 14;11 12 15 16] ;
i want to create a matrix of the nodes from the element and it's neighbouring nodes.
This is for a 2-by-2 and hope to implement it...
