7-16 Creating an ACM Model

7-16

Click on a column label to sort the table by that column.

Click again to reverse the sorting order.

“Constant” specifications are independent variables (inputs)

which can be changed. The table highlights fields which have

been changed from their defaults. Except for the numerical

properties (value, bounds etc.) properties have drop-down.

This, for example, allows you to change units of measurement

or specification (e.g. from constant to calculated).

You can insert new sub-tabs (right-click on an existing tab and

select Insert…). For each sub-tab you can define a query which

controls which variables appear in the sub-tab. Right-click

“Enter Query…” and define your query on the Enter Query dialog

box.

7.2.6 Parameters Tab

The Parameters tab displays multiple sub-tabs: “AllParameters”

plus the custom ACM tables which were checked for export and

Displays = “Parameters” or “Both” on the ACM Model Package

Properties forms. Each tab displays all the properties of the

parameters including: Name, Value, Units, Read Only,

description and base type. Click on a column label to sort the

table by that column. Click again to reverse the sorting order.

The “READ_ONLY” parameters are internal solver parameters

which provide information about the ACMOp. DOF (Degrees of

freedom), for example should have a value of 0, otherwise the

ACMOp has too many specs (negative DOF) or too few (positive

DOF).

You can create new tabs and control which parameters appear

on each tab using queries.

7.2.7 Equations Tab

Use this form to view attributes of equations in the ACM Op.

As in Aspen Custom Modeler products, the set of equations
