scenario_BasicOrbitMultiSat_MT#

Overview#

This script demonstrates how to use the Xmera v2.1 multi-threading to simulate a constellation of 16 spacecraft using 4 threads. The simulation scenario setup is very similar to scenario_BasicOrbitMultiSat. To setup the unique satellite orbits, the script here loops over all satellites an incrementally changes the orbit elements. The following Vizard screen capture illustrate the family of orbits being simulated.

Inside the run() command the number of threads is specified using:

TheScenario.TotalSim.resetThreads(numThreads)

With this basic setup it is assumed that each BSK process can run independently in a thread. Note that this script does not use any spacecraft flight software which is running in a separate process. The Xmera v2.1 multi-threading only functions for simulations where each Xmera process can be evaluated independently.

Warning

The Xmera v2.1 multi-threading does not have a thread-safe messaging system. This will be added in a later release.
