SIMTRAP User Manual - Starting a Simulation

The Client-Server dialog contains a scrollable Textfield, which displays messages according to the status of the current request passed to the Simtrap model-server. There are 3 buttons at the bottom of the dialog:

• Send
  Passes all the data specified in the current scenario to the model-server, and starts a new simulation. If the simulation could be started successfully the Textfield will display a RunID, which is used for data retrieval once the results of the simulation are available. Otherwise it will display some error messages according to the client-server protocoll.

• Delete
  Delete the simulation results for the current scenario on the model server. After issuing this request no further result requests are allowed.

• Kill
  Terminate the simulation run for the current scenario on the model server and delete all simulation results computed so far. After issuing this request no further result requests are allowed.

Protocol
The communication between the Simtrap CLIENT and the MODEL server is based on the TCP/IP and http protocols. The server uses a simple protocol based on keywords and associated values and data streams.
This protocol transfers model scenario specifications or parameters compiled and edited through the Simtrap Client user interface to the Model server. Results from the Model server are returned with the same protocol on demand, once the user enters the Simulation Result Page.
