NONSIM

Overview

The NONSIM function returns the value of a node with no assumptions applied to that node. Upstream nodes that affect the input still have their assumptions applied.

Use this function when you want to isolate the effect of assumptions placed on the node itself, while keeping upstream assumptions active.

Syntax

NONSIM('Node' [, "useVariablesFrom"])

Example usage: NONSIM('Revenue')

Parameters

Parameter	Description	Type	Required	Default
Node	Input node, specified using the node name in single quotes (e.g.`'Revenue'`)	Node reference	Yes	--
useVariables From	Determines which variable values are used in the calculation	Keyword	No	`"SCENARIO"`

useVariablesFrom options:

"SCENARIO": Uses variable values as overridden by the scenario. This is the default.
"PROJECT": Uses the original project default values instead of scenario overrides.

Output Shape

Aspect	Behavior
Dimensionality	Same as the input node.
Values	The input node's values computed without its own assumptions, but with upstream assumptions still applied.
Row count	Same as the input node's values without its own assumptions.

Watch Out

The input must be a single node reference. Combinations of operations (e.g. 'A' + 'B') are not valid.
NONSIM only removes assumptions from the specified node. Upstream nodes keep their assumptions. To remove assumptions from the node and all upstream nodes, use BASELINE instead.
If the model has multiple baselines, the baseline of the current scenario is used.
The PROJECT mode only applies project default variable values to nodes calculated within the NONSIM function. Upstream nodes outside the NONSIM call still use scenario variable values.

Examples

Baseline values without assumptions

This example shows the baseline result of multiplying two nodes when no assumptions or variable overrides are applied. The project default variable $MY_VAR is set to 10.

Project default variables: $MY_VAR = 10

Input node: Node 1

Year	Value
2025	$MY_VAR = 10
2026	$MY_VAR = 10
2027	$MY_VAR = 10
2028	$MY_VAR = 10

Input node: Node 2

Year	Value
2025	1
2026	1
2027	1
2028	1

Formula: 'Node 1' * 'Node 2'

Year	Value
2025	10
2026	10
2027	10
2028	10

These are the baseline results with no assumptions applied.

Values with scenario overrides and assumptions

This example shows how the same nodes look when a scenario overrides $MY_VAR to 20 and assumptions are activated on both nodes.

Variable override via scenario: $MY_VAR = 20

Input node: Node 1 (with overridden $MY_VAR as 'Base' and activated assumptions as 'Change')

Year	Base	Change	Result
2025	20	0	20
2026	20	10	30
2027	20	20	40
2028	20	30	50

Input node: Node 2 (with the initial measures as 'Base' and activated assumptions as 'Change')

Year	Base	Change	Result
2025	1	1	2
2026	1	2	3
2027	1	3	4
2028	1	4	5

Formula: 'Node 1' * 'Node 2'

Result node:

Year	*Base (Node 1 Node 2)**	Change	Result
2025	20 * 2	5	45
2026	30 * 3	5	95
2027	40 * 4	5	165
2028	50 * 5	5	255

Comparing SCENARIO vs PROJECT mode

This example shows the difference between the two modes. NONSIM removes only the Result Node's own assumptions (+5 Change) but keeps upstream assumptions on Node 1 and Node 2.

Formula: NONSIM('Result Node') = NONSIM('Result Node', "SCENARIO")

Year	→ NONSIM Result
2025	20 * 2 = 40
2026	30 * 3 = 90
2027	40 * 4 = 160
2028	50 * 5 = 250

The Result Node's own assumption (+5) is removed, but Node 1 and Node 2 keep their assumptions and the scenario's variable override ($MY_VAR = 20).

Formula: NONSIM('Result Node', "PROJECT")

Year	→ NONSIM Result
2025	10 * 2 = 20
2026	(10 + 10) * 3 = 60
2027	(10 + 20) * 4 = 120
2028	(10 + 30) * 5 = 200

PROJECT mode reverts $MY_VAR to the project default (10), so Node 1's base becomes 10 instead of 20. Node 1's upstream assumptions (Change = 0, 10, 20, 30) and Node 2's assumptions are still applied.
