Frequently Asked Questions
Q: What is the difference between FEA and CFD?
A: FEA is an acronym for finite element analysis and CFD is computational fluid dynamics. CFD characterizes the fluid and FEA characterized the solid.
Q: What is the numerical basis for LuxPCB?
A: LuxPCB is based on Finite Element Analysis (FEA) engine.
Q: What’s the advantage of LuxPCB thermal programs compared to the CFD based thermal programs?
A: The single most advantage of LuxPCB is the ease of modeling and data verifications. LuxPCB is created with the practical engineer’s perspective on thermal analysis.
Q: Do I need CFD for my PCB thermal analysis?
A: Yes and no. If the airflow near PCB is complex or difficult to estimate, a CFD program may help user calculate more accurate flow data. If you know the reasonable estimate on the airflow, FEA will give you accurate predictions.
Q: How is the flow characteristics represented in the FEA analysis?
A: In most cases, however, extensive experimental data area readily available that represents the flow characteristics into a single parameter called heat transfer coefficient, h.
