IS_VALID_STRUCT2 - Determine if the input structure is "valid" |
|---|
| 12 |
|
|---|
| 13 |
IS_VALID_STRUCT2 determines whether or not the input |
|---|
| 14 |
structure contains additional field data beyond the |
|---|
| 15 |
minimum valid fields checked for by <A HREF = "../3.FEM/is_valid_struct.html">IS_VALID_STRUCT</A>. |
|---|
| 16 |
Recall that a valid <A HREF = "../3.FEM/fem_grid_struct.html">FEM_GRID_STRUCT</A> contains (atleast) |
|---|
| 17 |
the following (NOT EMPTY) fields: |
|---|
| 18 |
|
|---|
| 19 |
.name,.e,.x,.y,.z,.bnd |
|---|
| 20 |
|
|---|
| 21 |
IS_VALID_STRUCT2 verifies the existence of .A, .B, .A0, |
|---|
| 22 |
and .T which are filled by <A HREF = "../3.FEM/belint.html">BELINT</A>, and of .ar filled by |
|---|
| 23 |
<A HREF = "../3.FEM/el_areas.html">EL_AREAS</A>. These additional FEM fields are needed by |
|---|
| 24 |
OPNML/MATLAB element-finding, basis and interpotion |
|---|
| 25 |
routines. |

| 26 |
