- Problem -
The multiple particle release tutorial showed that when the particle number was increased from 100 to 1000 and then again from 1000 to 10000, each time the maximum concentration decreased by half during the last sampling time period (0500). The 100,000 particle simulation was not shown, but the maximum concentration only decreased by 10% from the 10000 particle simulation, suggesting that the 10,000 particle release was sufficient. What particle number would be sufficient if the concentration grid was increased from 0.05 to 0.10 degrees?
- Hint - Retrieve cpart_control.txt and cpart_setup.txt and reconfigure.
- Solution - The 1000 particle 0.10 deg grid result is similar to the previous 10,000 particle 0.05 deg grid simulation. An explanation for this
result might be inferred from this illustration.
