About

PyAnsys Heart is a Python library developed by the Ansys Healthcare Research team to model the human heart using Ansys LS-DYNA software. Designed to support advancements in cardiovascular research, this tool enables detailed, patient-specific simulations of heart function, capturing complex interactions like fluid-structure-electrophysiology interaction (FSEI). These simulations replicate hard-to-measure features such as structural stress, electrical activity, muscle fiber orientation, and even account for anatomical elements like the pericardium, valves, and atria.
