Overview
This video covers the basics of internal flow analysis by predicting velocity and pressure distributions in fluid moving through an L-shaped pipe.
Internal Flow Analysis Workflow :
• Fluid Domain Extraction
Faces are created at the inlet and outlet, and the volume-extraction feature is used to isolate the actual fluid domain inside the solid pipe geometry.
• Boundary Conditions
An inlet velocity, outlet pressure condition, and wall conditions on the remaining pipe walls are applied to define the internal-flow setup.
• Result Analysis
Velocity and pressure contours and streamlines are reviewed using post-processing tools. The automatic min/max display and Probe tool are also used to examine local values at selected points, providing a quantitative view of pressure drop or velocity changes across a specific pipe section.
The video covers both fluid-domain extraction for internal flow and detailed examination of local simulation results.
