The shell section vertices take two forms, depending on whether or not the section is tagged as an "optimization section." If optimization is enabled, the following data names are available.

`shell_VertexCount`:

`shell_VertexYMaxima`- Pointer to the maximum y coordinates allowed for the vertices.
`shell_VertexYMinima`- Pointer to the minimum y coordinates allowed for the vertices.
`shell_VertexZMaxima`- Pointer to the maximum z coordinates allowed for the vertices.
`shell_VertexZMinima`- Pointer to the minimum z coordinates allowed for the vertices.

`shell_VariableCount`is non-zero then the following data names are pointers to arrays of length

`shell_VariableCount`:

`shell_VariableInitials`- Pointer to the current values of the variables.
`shell_VariableMaxima`- Pointer to the maximum values of the variables.
`shell_VariableMinima`- Pointer to the minimum values of the variables.
`shell_VariableNames`- Pointer to the names of the variables.

`shell_EquationCount`is non-zero then the following data are stored in the

`shell_Equations`variable whose size is equivalent to

`shell_EquationCount`:

`equation_DependentVertex`- The index of the dependent vertex.
`equation_IndependentCount`- The number of independent vertices in the equation.
`equation_IndependentVertices`- Pointer to the array of vertex indices used in the equation.
`equation_UnparsedEquation`- The actual raw text form of the equation.

`equation_IndependentCount`and

`equation_VariableCount`are non-zero, then the following data names are available:

`equation_VariableCount`- The number of design variables in the equation.
`equation_Variables`- Pointer to the array of design variables used in the equation.
