Summary O pen S im R oot is an open‐source, functional–structural plant model and mathematical description of root growth and function. We describe O pen S im R oot and its functionality to broaden the benefits of root modeling to the plant science community. O pen S im R oot is an extended version of SimRoot , established to simulate root system architecture, nutrient acquisition and plant growth. O pen S im R oot has a plugin, modular infrastructure, coupling single plant and crop stands to soil nutrient and water transport models. It estimates the value of root traits for water and nutrient acquisition in environments and plant species. The flexible O pen S im R oot design allows upscaling from root anatomy to plant community to estimate the following: resource costs of developmental and anatomical traits; trait synergisms; and (interspecies) root competition. O pen S im R oot can model three‐dimensional images from magnetic resonance imaging ( MRI ) and X‐ray computed tomography ( CT ) of roots in soil. New modules include: soil water‐dependent water uptake and xylem flow; tiller formation; evapotranspiration; simultaneous simulation of mobile solutes; mesh refinement; and root growth plasticity. O pen S im R oot integrates plant phenotypic data with environmental metadata to support experimental designs and to gain a mechanistic understanding at system scales.
