Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.

Fathom overview
What is Fathom?
Fathom is a fluid dynamic simulation software designed for engineers working with liquid and low-velocity gas piping and ducting systems. The software calculates pressure drop and flow distribution, allowing users to simulate individual system components and their interactions. Fathom integrates equipment characteristics analysis with the system's schematic representation.
Fathom empowers users to experiment with various operating conditions and scenarios. The software enables changing system input data, such as valve positions, pump operation, control set points, pressures, and temperatures. It can model a comprehensive range of system components for both design and operational cases, allowing users to vary the system line-up, open/close pipes and valves, turn pumps on/off, and set control valves to fail positions. Fathom also provides design alerts that automatically highlight output values outside the acceptable range for flow, pressure, velocity, and pump efficiency.
