NewtonWorks Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director: Toshikazu Yamanashi) has released the latest versions of its software series that supports the development of products involving tribology (friction, wear, lubrication): "NewtonSuite-OilFilm 2026.0", "NewtonSuite-RSCalc 2026.0", and "NewtonSuite-ASP-μ 2025.1".

Background and Purpose
In recent product development, there is a strong demand for developing products with lower friction in sliding parts to achieve carbon neutrality, and products that further reduce the environmental leakage of lubricants. Along with these, the importance of virtual testing (simulation) that replaces and complements actual machine testing between sliding mechanical parts is increasing more than ever.
In this update, we have implemented many new functions that enable analysis under complex conditions more in line with reality and reduce the modeling burden on users.
Major Update Topics
1. Fluid Lubrication Analysis Tool "NewtonSuite-OilFilm 2026.0"
In OilFilm, which analyzes the behavior of oil films, calculation accuracy has been improved and modeling has been simplified.
Translational Velocity Distribution Sliding Mode Implementation: It is now possible to consider non-uniform velocity distributions for sliding conditions that previously only covered uniform velocity distributions. The calculation of the "stretch term" generated by velocity differences depending on the location has been added to the fluid lubrication equation, enabling more advanced analysis.
Addition of Cylindrical Coordinate Data Points (Extension): It is now possible to create a film thickness model simply by specifying the width, diameter, and eccentricity of the inner and outer cylinders on the GUI without separately preparing a cylindrical surface data file. It also supports modeling that takes inclination into account.
2. Seal and Contact Analysis Tool "NewtonSuite-RSCalc 2026.0"
In RSCalc, which evaluates seal performance (leakage) and contact pressure distribution, design flexibility has been greatly improved.
New Profile for Radial Seal (RHL): "Two-way waviness with shear deformation (interpolation)" has been added to the contact profile. Previously, it was limited to cases with a single maximum value of contact pressure, but the new function can model complex contact pressure distributions with two or more maximum values, supporting a variety of radial seal designs.
Unit Conversion Function when using FEM Stiffness Matrix: When importing a stiffness matrix output from FEM software such as ADINA, ABAQUS, or ANSYS, unit conversion can now be performed. Data in "mm" or "m" units, common in CAD and FEM, can be smoothly converted to "μm" units, which are easier to handle in seal analysis.
3. Surface Roughness Analysis Tool "NewtonSuite-ASP-μ 2025.1"
ASP-μ, which analyzes surface texture from a microscopic perspective, visualizes the real contact area, which differs from ideal Hertzian contact.
Surface Texture Analysis (RSP) and Micro Contact Analysis (CA): Provides an RSP mode that calculates surface characteristics from actually measured roughness data, and a CA mode that performs contact analysis considering the deformation of unevenness. The calculated roughness information can be seamlessly linked as input data for OilFilm and RSCalc.
[Operating Environment]
OS: Windows 11 or later (64-bit)
Recommended Environment: 80GB or more of free storage space, multi-core CPU to utilize parallel computing
Future Prospects
"NewtonSuite" will continue to enhance its functions to incorporate more advanced physical phenomena, such as consideration of viscosity changes (temperature and pressure dependence), thermal fluid lubrication, and handling of gases (density changes). We are also planning to add a wear calculation mode and enrich output functions (clearance volume, wear volume, etc.), strongly promoting DX in sliding part design.
