Measuring amount of contaminants filtered

Hi! How do I measure the amount of contaminants filtered through a mesh (ex. percentage CO2 filtered)? Also, can I test my own contaminants like lead? Thank you!

Hi there, this is Fillia :slight_smile: You can use a volumetric passive scalar source, have a look here: Passive Scalar Sources | Advanced Concepts | SimScale
Also, this tutorial uses this method: Car Park Contamination Simulation Tutorial | SimScale
You can set the properties of the model according to your own contaminant.

Best regards,
Fillia
