Hello everyone,

 

I am very new to CFD (Student), and wanted to learn it for the fun of it. I've made a fin and tube condenser coil, and I tried to do a simple CFD on it, but I keep getting 3 warnings.

1. Unresolved boundary Condition, Condition name : Environment Pressure 1, Inlet Mass Flow 1

2. Unresolved Region, Condition name: Fluid Subdomain 1.

 

Basically I want to simulate a airflow through the condenser at 96F and 2700 CFM. The working fluid inside the Condenser is suppose to be R410A with inlet givens: 350 PSI, 140F Superheated, mass flow: 260lb/hr. I want to know the heat transfer coefficient of the aluminum fins. I set this up as a external flow.

 

I do not know what I am doing wrong, Please enlighten me with knowledge .
