CURL - Compute the CURL of a FEM 2-D vector field |
|---|
| 13 |
|
|---|
| 14 |
CURL(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,u,v) computes the curl of a 2-D |
|---|
| 15 |
vector field (u,v) (curl X (u,v)) over the FEM domain |
|---|
| 16 |
specified by <A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>. The result is a 2-D |
|---|
| 17 |
scalar field containing the curl, returned to the workspace. |
|---|
| 18 |
|
|---|
| 19 |
The computed quantity is: crl=dv/dx - du/dy |
