1. A computer implemented method of modelling the degradation of at least a component having a non-planar surface profile with a granular structure within an abrasive environment, the method comprising:
obtaining a 3D scan of a surface of athe component, with data from the 3D scan being processed into a surface image,
processing the surface image of the component,
determining surface properties of the component,
inputting the 3D scan data into a trained prediction model,
predicting a performance parameter of the component, and,
simulating a surface evolution over time or use of the component, and
determining when the component should be replaced based on the simulated surface evolution, wherein
simulating the surface evolution includes calculating grain properties of grains in the granular structure of the component, classifying each of the grains based on the grain properties, and deleting at least a portion of each respective grain based on the classification.
