Every pipeline, pressure vessel, and structural support in your facility operates in a world where fluid forces and mechanical behaviour are inseparable. A surge in flow, a slug of liquid, a sudden pressure spike — these events don't just stress your fluid systems, they physically deform, vibrate, and fatigue your structures in ways that traditional engineering analysis often fails to capture.
That gap between what your analysis predicts and what actually happens in the field? Fluid Structure Interaction (FSI) closes it.
The Problem with Conventional Analysis
Most structural and process analyses treat fluid loads and mechanical responses as separate problems. You calculate pressures, then apply them as static loads on a structure. But in reality, the fluid and structure are constantly reacting to each other — creating a bidirectional, closed-loop relationship between fluid movement and structural dynamics. Ignoring this two-way interaction leads to unexpected failures, conservative overdesign, or both.
