Hi everyone,
I want to model a volume of some contaminant as a spill. As I know, the only way is to apply it as mass concentration (in mg/L) into nodes. If I select all 6 nodes of a triangular prism element, which has 1000 L volume, and set the concentration to 1000 mg/L in every node, does it mean that I have modeled 1000 grams of mass in that area?
What would be the concentration in neighboring elements and nodes? Is concentration jumps from 1000 to zero from the selected node to other nodes around?
