If the finite element model shown below represents heat conduction in axisymmetric or plane geometries then which option is not true? (- frac{ partial}{ partial x}(a_{11} frac{ partial u}{ partial x}+a_{12} frac{ partial u}{ partial y})- frac{ partial}{ partial y}(a_{21} frac{ partial u}{ partial x}+a_{22} frac{ partial u}{ partial y}) ) +a00u-f=0 |
| A. | u is temperature |
| B. | a<sub>11</sub>, a<sub>22</sub> are conductivities in x, y directions |
| C. | f is internal heat generation |
| D. | a<sub>00</sub>=1 |
