modelDiscretizedModels

Information

Discretized models are organized in a consistent numbering format. When selecting a particular geometry, pay particular attention to the dimensions being specified as this dicates the corresponding dimenions in all underlying variables.

For example.

• 1D - Cylinder_1D_r: r = 1; therefore variables such as crossAreas_1[nR+1] corrseponds to the interface between variable in the first dimension path "r".
• 2D - Cylinder_2D_theta_z: theta = 1 and z = 2; therefore variables such as crossAreas_1[nTheta+1,nZ] corrseponds to the interface between variable in the first dimension path "theta".
• 3D - Cylinder_3D: r = 1, theta = 2, and z = 3; Note the 3d components do not contain a specified dimension association. Consistent order is then assumed:
• • Planar - x,y,z
  • Cylinder - r, theta, z
  • Sphere - r, theta, phi

Notes

• Fluid and HeatAndMassTransfer discretized models are not exactly the same,though the general nodalization approach is similar. This representation is more applicable to the HeatAndMassTransfer models.
• The crossAreas* variables represents the area between disretized nodes. It therefore exists only for the discretized dimensions.
• The surfaceAreas* variables represent the outer areas of the body in non-discretized dimensions only. This permits interaction with the body in these additional areas which may be important for a particular problem.
