Starting a PWC Run and Accessing Run Information

In a Pedestrian Wind Comfort (PWC) analysis, before starting a simulation run, you need to ensure that the simulation tree reflects the minimum setup completion. See below:

This is the minimum required setup for a PWC simulation to run. Entities not marked with a complete state are optional.

When you are confident that your simulation settings are accurate and ready to be solved then you can start a simulation run. To start a simulation you simply need to click the ‘+’ button at the bottom of the simulation tree next to Simulation Runs. This will lead to a New run window. Click on ‘Start’.

This automatically starts a parallel simulation for each wind direction and once finished, will compile all the results into statistical results based on the comfort criteria.

Did you know?

The solver for PWC analysis in SimScale incorporates the lattice Boltzmann method (LBM). The mesh used for domain discretization is a Cartesian mesh.

Once the simulation has been initialized, it will give a readout of the key automatic settings applied such as the wind tunnel size, Reynolds scaling factor, mesh and time step sizes, etc. Checking into the Event log at the end of a successful simulation should reveal the following:

Typically, a minimum cell size of ~1 $$m$$ leads to good results. For accurate, mesh independent results, typically a value of around 0.5 $$m$$ will be displayed.
