SIMILE : Modeling tool
  • Modeling & river systems
  • SIMILE as a modeling tool

- What it is & what can we use it for?

● Navigate in SIMILE

- Example: Bank account

• Visual modeling environment

- Build model without learning programming

- Display concept & relationship using diagram:

‘stocks’, ‘flows’ and ‘influences’

- GUI for simulation control & specifying inputs

- Visualize & compare the model behaviors in

graphs, tables

• What can we use it for?

- Rate expressions for biological, chemical, or physical processes (differential equations)

Ex: Mass balance or accounting, Growth dynamics,

Respiration

- Scenario analysis

Ex: Effect of flow velocity on gas exchange between

river-atmosphere

slide6

Navigate in SIMILE

• Start > All Programs > Simulistics > Simile v4.4

slide7

Navigate in SIMILE

• Overall modeling scheme

Run-time environment

Enter values for

parameters/stocks

or

Describe equations

Choose output display

&

Set run conditions

Conceptual

design

(diagram)

Run model

• Tutorial: http://simulistics.com/tutorials/index.htm

Example: Bank account

bank account conceptual design
Bank account: Conceptual design

Stock or compartment: an account

Flows: Interest & withdrawal

Parameter: Interest rate

slide9

Bank account: Enter values for parameters/stocks or describe equations

• For time-dependent model

- Set initial value for stocks (compartments)

- Define parameters (flows & variables)

Direct values

Equations to describe

behaviors

Constant

Time-series

Variables that influence

the parameter

slide10

Run-time environment

Create plot

Create table

Run

  • 1. Set execution condition in ‘Run
  • control’ & ‘Run settings’
  • 2. Set display preference
  • 3. Run

List of parameters/stocks
