Template:RT3D Code Reaction Workflow

1. Select package coding approach.
Dynamically linked library (DLL) DLL option. Linked subroutine option

2. Select method for coding a new user-defined package.

In the first method, all reaction parameter values are explicitly assigned within the reaction module prior to compilation. This is not an efficient method since it requires recompilation of the reaction routine whenever a reaction parameter value is modified. However, this method is recommended for testing a new reaction module with the BATCHRXN utility. In the second method, all of the reaction parameter values are spatially constant but are assigned/modified externally, as input data, via the RCT file (to run RT3D) or batch.in file (to run BATCHRXN). In the third method, some or all of the reaction parameters are treated as spatially variable (i.e., a different value may be assigned to each cell). The parameter values should be externally assigned/modified as input data via the RCT file. This option should be used with caution because it may require significant computer resources, both execution time and memory.

3. Edit source code of the reaction module.
Open and edit the package file using an ASCII editor (Notepad, WordPad, etc.).

4. Compile source code.
Use a command prompt to compile the DLL file.
