SET_EXTERNAL_PARAMETER

This command is for the PARROT module.

Optimize model parameters of the so-called external models, which may not be as fully-implemented/integrated parts inside the GIBBS system and thus are independently defined within user-specified/written source codes. This command makes links between the PARROT optimizing variables and external model parameters.

In order to be able to build the specified external model and to use this SET_EXTERNAL_PARAMETER command, it requires you to first write codes for a preferred external model (as it is not within the standard GIBBS system of the Thermo‑Calc software) and then provide it to a consultant at Thermo‑Calc Software AB for the purpose of including the external model in a separate DLL that is interactively connected to the software. For more information, see theConsultancy page on our website.

Syntax	set_external_parameter
Prompt	External name: <Parameter name in the external model> Correctly specify the parameter name defined within a specified/written external model.
	As optimizing variable number: <n> Give the number of the PARROT optimizing variable, which should have a unique link to the specified parameter name of the external model. For example, @@ Link PARROT variables to CAM parameters: SET-EXTER-PAR GT(SLAG_A,O-2,SI+4,CA+2) 1 SET-EXTER-PAR ET(SLAG_A,O-2,SI+4,CA+2) 2 SET-EXTER-PAR EXT(SLAG_A,O-2,SI+4,CA+2) 3

Syntax

set_external_parameter

Prompt

External name: <Parameter name in the external model>

Correctly specify the parameter name defined within a specified/written external model.

As optimizing variable number: <n>

Give the number of the PARROT optimizing variable, which should have a unique link to the specified parameter name of the external model.

For example, @@ Link PARROT variables to CAM parameters:

SET-EXTER-PAR GT(SLAG_A,O-2,SI+4,CA+2) 1

SET-EXTER-PAR ET(SLAG_A,O-2,SI+4,CA+2) 2

SET-EXTER-PAR EXT(SLAG_A,O-2,SI+4,CA+2) 3
