Tufts University researchers, led by physics professor Tim Atherton, have developed Morpho, an open-source software designed to model and optimize soft materials. It addresses challenges in predicting their behavior under various forces. Unlike traditional software for rigid structures, Morpho employs finite element methods to simulate complex responses of soft materials, enabling applications such as artificial heart design and shape-shifting robotics.
The software also tackles packing problems and heterogeneous systems, offering a versatile tool accessible to engineers and researchers without extensive training. Free and easy to use, Morpho provides a comprehensive solution for optimizing designs involving flexible and fluidic materials across diverse fields.
Challenges in Modeling Soft Materials
Soft materials such as biological tissues, hydrogels, and shape-shifting fluids present unique challenges due to their flexibility and responsiveness to external forces. Unlike rigid structures, these materials can undergo significant deformation under stress, making their behavior less predictable. Factors like compression, liquid flows, pressure changes, and vibrations complicate the prediction of their final shapes, requiring specialized computational approaches.
Traditional modeling tools are unsuited for soft materials as they are primarily designed for rigid structures. This limitation forces engineers and researchers to develop custom mathematical formulations for specific applications, a time-consuming process requiring advanced expertise.
Development of Morpho Software
The development of Morpho addresses these challenges by providing an open-source platform tailored explicitly for soft material modeling. Morpho employs the finite element method (FEM), a numerical technique that breaks down structures into more minor elements like triangles or tetrahedrons. This allows for solving complex equations related to material behavior under various forces, including compression, tension, and fluid flow.
Morpho’s implementation of FEM enables accurate simulation of responses to external forces while handling nonlinearities inherent in soft materials, such as large deformations and anisotropic behavior. The software’s open-source nature encourages collaboration and customization, making advanced modeling techniques accessible without relying on expensive proprietary tools.
Finite Element Method for Soft Material Simulation
The finite element method (FEM) is a numerical technique used to solve complex equations related to material behavior under various forces. By dividing structures into more minor elements like triangles or tetrahedrons, FEM allows researchers to model deformation, stress distribution, and other mechanical behaviors in soft materials.
Morpho’s implementation of FEM enables precise modeling of responses to external forces, including compression, tension, and fluid flow. It handles nonlinearities common in soft materials through iterative methods, accounting for changes in properties as the material deforms. This capability is particularly valuable for applications involving biological tissues, hydrogels, and other complex materials.
Applications Beyond Soft Materials
While Morpho was developed with soft materials in mind, its versatility allows it to be applied to a wide range of fields beyond traditional soft material modeling. For example, Morpho can be used in aerospace engineering to simulate the behavior of flexible structures under various loads or in civil engineering to analyze the deformation of soil and other materials.
Morpho’s accessibility and open-source nature encourage collaboration and customization, making advanced modeling techniques available to a broader audience. This democratization supports innovation across disciplines where understanding material behavior is critical.
Ease of Use for Researchers
Morpho is designed with ease of use in mind, featuring an intuitive interface, comprehensive documentation, and tutorials that facilitate adoption even for those less experienced with FEM. The software’s computational efficiency is achieved through optimizations like parallel processing, making it suitable for resource-intensive simulations.
Validation against experimental data ensures Morpho’s accuracy, which is particularly important in biomedical applications where errors can have serious consequences. By providing a precise tool for modeling deformation and stress distribution, Morpho empowers researchers to tackle complex problems effectively across various disciplines.
