About J-OCTA

About J-OCTA

J-OCTA can be used at the forefront of materials and life science R&D

J-OCTA is a multi-scale simulation software that predicts properties from the atomistic to the micrometer scale on a computer for research and development of a wide range of high-performance materials such as resins, rubbers, nanocomposites, thin films, inks, and batteries, and in the life science field such as drug discovery and pharmaceutical formulation.

It can be used as a knowledge discovery tool to understand the mechanisms of complex phenomena that could not be understood by experiments alone, and as a data generation tool for informatics.

It is also possible to link simulators of different scales on a common platform and combine data science functions to support cutting-edge research and development.

Structure of J-OCTA

To use J-OCTA’s functions, “J-OCTA platform” is necessary, except for the QSPR-only version.

J-OCTA Student Edition

The J-OCTA Student Edition is a free software that consists of the basic functions from the J-OCTA advanced simulation system, and it is useful for small calculation and/or validation. Anyone can use the student edition for free and without any license application and/or registration. The J-OCTA Student Edition is useful as both the atomistic molecular modeling tool for J-OCTA simulations and as a support tool for your analyses. You also can try to evaluate the capability of J-OCTA as a provisional test prior to the formal introduction.

Commissioned and consulting business

JSOL provides a simulation commission service to support OCTA/J-OCTA usage that includes estimating the physical properties of soft materials, primarily resin or rubber polymer materials, and understanding the material mechanisms.

The commission service is a comprehensive service that includes a preliminary survey, modeling, input data generation, simulation, and analysis of the simulation result. JSOL provides the input data used for the simulation along with the final report.

Customized service for OCTA/J-OCTA can also be provided.

Please contact us for details.
