Tufts University researchers have developed an open-source software package called "OpenSM" designed to simulate the behavior of soft materials like gels, polymers, and foams. This software leverages state-of-the-art numerical methods and offers a user-friendly interface accessible to both experts and non-experts. OpenSM streamlines the complex process of building and running simulations of soft materials, allowing researchers to explore their properties and behavior under different conditions. This freely available tool aims to accelerate research and development in diverse fields including bioengineering, materials science, and manufacturing by enabling wider access to advanced simulation capabilities.
A March 4, 2025, Tufts Now article announces the release of an open-source software package specifically designed for modeling the complex behaviors of soft materials. Developed by a team of researchers led by Aleksandar Donev at the Courant Institute of Mathematical Sciences at New York University and including collaborators from Tufts University, the software, named "mSoft," addresses a significant gap in the existing landscape of material modeling tools. Traditional software packages often struggle to accurately capture the unique characteristics of soft materials, which encompass a broad range of substances like polymers, foams, gels, and biological tissues. These materials, distinguished by their deformability and responsiveness to external stimuli, present unique challenges for computational modeling due to their intricate internal structures and the wide range of length and time scales involved in their behavior.
mSoft offers a comprehensive suite of tools for simulating these intricate materials. It employs specialized algorithms and numerical methods optimized for handling the complexities of soft matter physics, including the interplay of thermal fluctuations, hydrodynamic interactions, and intricate molecular architectures. The software is particularly adept at modeling systems involving numerous interacting particles, capturing the emergent collective behaviors that arise from these interactions. This capability is crucial for understanding phenomena like self-assembly, phase transitions, and the mechanical properties of these materials.
The decision to release mSoft as open-source software signifies a crucial step towards democratizing research in this field. By making the software freely available, the researchers aim to foster collaboration and accelerate scientific progress. Researchers worldwide can now access, utilize, and contribute to the development of mSoft, benefiting from the collective expertise of the community. This open-source approach not only facilitates the sharing of knowledge and resources but also promotes transparency and reproducibility in scientific research. The availability of a robust, open-source platform like mSoft is expected to empower researchers across various disciplines, from materials science and engineering to biophysics and medicine, to delve deeper into the fundamental properties of soft materials and pave the way for innovative applications in diverse fields. The article highlights the potential impact of mSoft in advancing our understanding of complex biological systems and developing next-generation materials with tailored properties.

The Hacker News post titled "Open source software for modeling soft materials," linking to a Tufts University article about the open-source software package "OpenSM," generated several comments discussing its potential and limitations.
One commenter expressed excitement about the project, particularly its potential for simulating robotic manipulators made of soft materials. They specifically mentioned the challenges in accurately modeling these kinds of robots due to the complex interactions of deformable materials. The open-source nature of OpenSM was highlighted as a significant advantage, allowing for community contributions and potentially accelerating development.
Another commenter focused on the computational intensity of such simulations. They questioned the scalability of OpenSM, especially for complex scenarios. They pondered whether the software relied on traditional Finite Element Analysis (FEA) methods and speculated on the potential benefits of using Machine Learning (ML) to speed up the simulation process. While acknowledging the current limitations, they expressed hope that the project would explore ML integration in the future.
A subsequent reply to this comment agreed on the computational challenges inherent in soft material simulation, specifically highlighting the non-linear behavior of these materials. They suggested that Graphical Processing Units (GPUs) could be leveraged to improve performance and pointed out that some existing FEA packages already use GPUs effectively. This comment also touched upon the complexity of constitutive models for soft materials, adding another layer to the computational difficulty.
Another commenter shifted the discussion slightly by questioning the practical applicability of soft robotics. They pointed out the limitations of current soft robotic actuators in terms of speed and strength, suggesting that these constraints limit their usefulness for real-world tasks. This comment sparked a brief debate about the niche applications of soft robotics, with a reply arguing that fields like medical devices and human-robot interaction could benefit from the gentle and adaptable nature of soft robots.
Finally, a comment lauded the use of the MIT license for OpenSM. This commenter appreciated the permissiveness of the license, contrasting it with the GNU General Public License (GPL) and highlighting the freedom it offers for both academic and commercial use. They specifically mentioned that the MIT license encourages broader adoption and contribution, benefiting the open-source community as a whole.
In summary, the comments on the Hacker News post generally expressed enthusiasm for the OpenSM project, but also acknowledged the inherent difficulties in simulating soft materials. The discussion touched upon computational challenges, the potential of ML and GPU acceleration, the limitations and niche applications of soft robotics, and the benefits of the MIT license.
