REDUCE compute a bandwidth-reduced FEM domain connectivity list |
|---|
| 12 |
|
|---|
| 13 |
REDUCE reduces the bandwidth of a FEM element list |
|---|
| 14 |
using the symmetric reverse Cuthill-McKee bandwidth reduction |
|---|
| 15 |
algorithm. It employs the MATLAB routine SYMRCM to perform |
|---|
| 16 |
the reordering and then permutes the remaining input arguments |
|---|
| 17 |
according to the new node numbering. |
|---|
| 18 |
|
|---|
| 19 |
INPUT: e - element list; 3 (.tri) or 4 (.ele) columns wide (REQ) |
|---|
| 20 |
x,y,z - nodal coordinate lists (OPT) |
|---|
| 21 |
|
|---|
| 22 |
OUTPUT: re - reordered element list (REQ) |
|---|
| 23 |
rx,ry,rz - reordered nodal coordinates (OPT) |
|---|
| 24 |
rb - reordered boundary segment list (OPT) |
|---|
| 25 |
perm - permutation list (REQ) |
|---|
| 26 |
|
|---|
| 27 |
CALL: REDUCE requires one of the following calling formats: |
|---|
| 28 |
1) [re,perm]=reduce(e); |
|---|
| 29 |
2) [re,rx,ry,rz,rbnd,perm]=reduce(e,x,y,z); |
