Comments
- The nb_integr must be equal to the number of integration points given in the shell property.
- The npg must be set according to the formulation which is used in the shell property.
- The number of values
alpha_ij given must be equal to
.For i = 1
- Alpha_11 for integration point = 1
- Alpha_12 for integration point = 2
- ...
- Alpha_1j for integration point = j
For i = 2- Alpha_21 for integration point = 1
- Alpha_22 for integration point = 2
- ...
- Alpha_2j for integration point =j
- ...
For i = npg- ...
