摘要: Abstract Fungi develop structures that interact with their surroundings and evolve adaptively in the presence of geometrical constraints, finding optimal solutions for complex combinatorial problems. The pathogenic fungus Ophiocordyceps constitutes a perfect model study constrained interactive networks. Modeling these networks is challenging due to highly coupled physics involved interaction moving boundaries. In this work, we computational phase-field elucidate mechanics emerging properties observed fungal We use variational approach derive equations governing evolution time mycelium biomass nutrients medium. present an extensive testing our model, reproduce growing decaying phenomena, capture spatial temporal scales. explore variables interplay mechanism leads different colony morphologies, explain abrupt changes patterns laboratory. apply simulate analogous processes as it grows through confined geometry depletes available resources, demonstrating suitability formulation class biological
