In this example, we simplify Case01 setup by forgoing the use of parameter Block_height. Instead, we replace this parameter name by directly using the expression Height+1 in the Nodal_data data structure. Note that the parameter names and expressions are case-insensitive. Also, underscore is used to represent space within parameter names and expressions.
Basic Set Up: Data File Description
The data file for the project is in : ParDef_001\Case02\Data. The key data structures relevant to the definition of parameter definition for the current example are:
•Parameter_definition to define parameter names and values. •Global_loads to replace load value with parameter name "Load". •Nodal_data to replace coordinate points with parameter names "Length", "Height", "Block_width", and local expression "Height+1".

Parameter_definition
•Defines parameter names and parameter values

Global_loads
•Defines the surface load value through parameter name

1Parameter name Load is put under Global_loads to define the normal surface load on the concrete block.

Nodal_data
•Defines coordinate points through parameter name

1Parameter names Length, Height, and Block_width are placed accordingly under Nodal_data to define domain geometry. 2Expression Height+1 is defined locally to represent the height of the concrete block. |
