Part 6: Incorporating Additional Examples
Let’s extend the sydevs-tutorial project with existing examples.
- Copy the demo folder in the external/sydevs-[version]/src/examples directory, and paste the folder into the src/nodes directory.
- In the src/nodes/demo/building7m folder, find main.cpp and move it into a new building7m_simulation folder within src/simulations. Open the file and in the
#includestatement, replace the textexampleswithnodes. - In the src/nodes/demo/queueing folder, find main.cpp and move it into a new queueing_simulation folder within src/simulations. Open the file and in the
#includestatement, replace the textexampleswithnodes. - In the src/nodes/demo/workers folder, find main.cpp and move it into a new workers_simulation folder within src/simulations. Open the file and in the
#includestatement, replace the textexampleswithnodes.
You should now have the following directory structure.
sydevs-examples/
bin/
...
external/
...
src/
examples/
demo/
building7m/
queueing7/
workers/
getting_started/
waveform/
simulations/
building7m_simulation/
first_simulation/
queueing_simulation/
setting_up/
simulation_with_ports/
workers_simulation/
Open CMakeLists.txt and add the following instructions to the SyDEVS Nodes section.
set(BUILDING7M_DIR ${NODES_DIR}/demo/building7m)
file(GLOB BUILDING7M_HDRS "${BUILDING7M_DIR}/*.h")
set(QUEUEING_DIR ${NODES_DIR}/demo/queueing)
file(GLOB QUEUEING_HDRS "${QUEUEING_DIR}/*.h")
set(WORKERS_DIR ${NODES_DIR}/demo/workers)
file(GLOB WORKERS_HDRS "${WORKERS_DIR}/*.h")
aux_source_directory(${WORKERS_DIR} WORKERS_SRCS)
Also add the following to the Simulations section at the bottom, and save.
set(BUILDING7M_SIMULATION_DIR ${SIMULATIONS_DIR}/building7m_simulation)
aux_source_directory(${BUILDING7M_SIMULATION_DIR} BUILDING7M_SIMULATION_SRCS)
add_executable(building7m_simulation ${BUILDING7M_SIMULATION_SRCS} ${BUILDING7M_HDRS})
target_link_libraries(building7m_simulation SyDEVS-static)
add_custom_command(TARGET building7m_simulation POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy
${PROJECT_SOURCE_DIR}/${BUILDING7M_DIR}/building7m.png
$<TARGET_FILE_DIR:building7m_simulation>/.)
set(QUEUEING_SIMULATION_DIR ${SIMULATIONS_DIR}/queueing_simulation)
aux_source_directory(${QUEUEING_SIMULATION_DIR} QUEUEING_SIMULATION_SRCS)
add_executable(queueing_simulation ${QUEUEING_SIMULATION_SRCS} ${QUEUEING_HDRS})
target_link_libraries(queueing_simulation SyDEVS-static)
set(WORKERS_SIMULATION_DIR ${SIMULATIONS_DIR}/workers_simulation)
aux_source_directory(${WORKERS_SIMULATION_DIR} WORKERS_SIMULATION_SRCS)
add_executable(workers_simulation ${WORKERS_SIMULATION_SRCS} ${WORKERS_HDRS} ${WORKERS_SRCS})
target_link_libraries(workers_simulation SyDEVS-static)
When the project is re-built, there should be an executable named building7m_simulation which produces the following results.

There should also be an executable named queueing_simulation which produces the output below.

The building7m (7-meter building) example demonstrates a number of features of the SyDEVS library.
- Composite Node with Ports and Inward/Outward Links: building_dynamics_node.h
- Composite Node containing a Composite Node (hierarchy): building_closed_system.h
- Multidimensional Arrays: thermodynamics_node.h
- Standard International (SI) Units: occupant_node.h
The queueing example is notable in that it features a commented header file demonstrating each of the four types of nodes.
- Atomic Node: queueing_node.h
- Composite Node: two_stage_queueing_node.h
- Collection Node: parallel_queueing_node.h
- Function Node: plus_node.h
The workers example is described in a separate tutorial, Agent-Based Modeling with Symmetric DEVS (Download PPTX).
Take a few minutes to familiarize yourself with these examples, then proceed to the final part of the tutorial. In Part 7, you will be challenged to make several enhancements to the building7m example.
