Transcript Development of a High-Resolution Virtual Terrain for use

Realtime Technologies, Inc.
Distributed Simulation Training
April 2005
Purpose
 Introduce distributed simulation concepts. Build
and test a distributed simulator.
Network Properties
 Must set up your
IP address and
Subnet mask
Configure SimCreator Network
 The IP Broadcast Address is based
on your IP address and the subnet
mask. Subnet numbers that are
zero become 255 in the IP address
to create the broadcast address:
IP Address: 192.168.0.1
Subnet: 255.255.255.0
-> Broadcast Address:
192.168.0.255
 Login Name must be a Windows
user with correct password
 Storage path must exist in the ftp
folder
Install IIS
 Go to install
windows
components and
select IIS to
install (if it is
checked already
then it is already
installed)
Set Up IIS Manager
 Inside the Control
Panel
 Inside of
Administrative Tools
Configure IIS
 Select ftp sites
 Select Default FTP
site
 Right click and
select properties
Configure IIS
 Unclick
Anonymous
Connections
Configure IIS
 Turn on write
permissions to
home directory
Configure SimCreator
 Make sure ftp
path is the same
as the local path
in IIS
Build a Simple Simulation
 Compile a model
by selecting:
Code -> Compile
 Select the
appropriate host
Run the Model Over the Network
 Select:
Run->Execute
 Make sure the
appropriate host
is selected and
the interpreter
flag is turned off
Compile a Generic Model Over the
Network
 Open Standard
Library
 Select:
Code->Compile
Generic
 Select the
appropriate host
Run the Previous Model Over the
Network with Interpreter
 Select:
Run->Execute
 Make sure the
appropriate host
is selected and
the interpreter
flag is turned on

Component Data
COMPONENT Local_Ramp
InitValue [0][0] = 0 [ND] Initial Value Before Ramp
RampTime [0][0] = 1 [sec] Starting Time of Ramp
Slope [0][0] = 1 [ND/sec] Ramp Slope
COMPONENT Remote_Ramp
InitValue [0][0] = 0 [ND] Initial Value Before Ramp
RampTime [0][0] = 1 [sec] Starting Time of Ramp
Slope [0][0] = 1 [ND/sec] Ramp Slope
COMPONENT Remote_Gain
Gain [0][0] = 1 [ND] Gain
Run the Simulation
 If the generic
model has all
the
components
can run

Rerun With Interpreter On
 If the interpreter
is compiled on
every machine.
Then you don’t
have to compile
distributed
models. Just run
them in
interpreted
mode.
