Defining Physics
After you create the mesh for the fluid domain to study, you can define the physics and the conditions for the problem. The physics specifications are handled in Creo Flow Analysis using modules. You can add these modules from the Physical Model Selection dialog box using one of the following methods:
• Click 
Flow Analysis > 
Physics Module. The Physical Model Selection dialog box opens.
Flow Analysis > Physics Module. The Physical Model Selection dialog box opens.• Under Domains, right-click a fluid domain and click Select Physical Models. The Physical Model Selection dialog box opens.
The modules available under Available Modules can be added to the simulation. The modules available in Creo Flow Analysis are:
• Flow
• Heat
• Particle
• Dynamics
• Species
• Common
