[Swarm-Support] =Problem_on_Urban Simulation_Using Swarm

[Stone Oliver]

Hi, list.

In recent days my colleagues and I are doing research work on

urban socio-spatial simulation using Swarm.

Here is the result operation.

 

An unexpected exception has been detected in native code outside the VM.
