Computational Mechanics International Inc.

Computational Mechanics International Inc., doing business as Computational Mechanics International, is a for-profit engineering simulation software vendor based in Billerica, Massachusetts, that sells perpetual and node-locked software licenses and related technical support to the federal government as a prime contractor (93% of recent awards), competing full-and-open with no set-aside designations across its active footprint. The company has been SAM-registered since 2002 and serves a narrow, high-specificity customer set dominated by naval engineering commands.

Computational Mechanics International's capability portfolio centers on the BEASY software suite for corrosion analysis, cathodic protection systems, impressed current cathodic protection (ICCP) modeling, and related engineering simulation tools, alongside complementary products including Corrosion Manager, PolCurveX, GID Modeler, and specialized coating degradation APIs. The company delivers node-locked licenses, perpetual licenses, and software renewal and support services. Recent prime work includes a $196,363.64 firm-fixed-price purchase order from Naval Sea Systems Command (NAVSEA) awarded in June 2023 for BEASY Corrosion & CP and ICCP software and licensing services (completion April 2026), a $43,956 purchase order from Naval Air Warfare Center in June 2025 for three indefinite node-locked licenses (Corrosion Manager, PolCurveX, and GID Modeler), a $24,981.50 Office of Naval Research purchase order from November 2025 for a Coating Degradation API standard version, and recurring annual BEASY license renewals with NASA's Shared Services Center valued in the $18,000–$20,000 range (most recent award March 2026, $20,675.70).

Customer concentration is acute and Navy-dominated. The top five customer entities account for 72% of awards by count and 99% of combined potential value: Naval Sea Systems Command leads in dollars ($854 thousand across eight awards), Naval Air Warfare Center follows with eleven awards totaling $266 thousand, and NASA's Shared Services Center, the Office of Naval Research, and Naval Facilities Engineering Command round out the active set. The Navy accounts for roughly 31 of the 43 total awards in the recent footprint. Awards are predominantly small purchase orders in the $18,000–$196,000 range, with combined potential value across the entire active footprint at $1.3 million but combined obligated dollars at $3.6 million, indicating that invoiced performance has exceeded stated contract ceilings across the portfolio. The most recent award cycle shows increasing activity — one award in 2018, then two each in 2023 and 2024, then five in 2025 — with only one award in 2026 year-to-date. Recompete risk is minimal: only one award (valued at $21 thousand) completes in the next twenty-four months.

In its subcontractor role, Computational Mechanics International delivers engineering simulation and modeling support to Luna Labs USA LLC on research-and-development and model-framework tasks (awards October 2025 and June 2025) and to The Boeing Company on a naval aircraft structural service-life prediction tool incorporating mechanical, environmental, and galvanic stress analysis (award March 2024). The company's federal business is characterized by sole-source or limited-competition awards from repeat customers with specialized technical requirements in naval engineering and corrosion management, with no exposure to full-and-open competitive GWAC or IDIQ work.
