Numerical simulation of bone remodelling around implants is computationally demanding, especially for models based on high-resolution micro-CT data. Traditional approaches either reduce model resolution, which limits accuracy at the microstructural level, or employ voxel-based models that significantly increase computational cost due to stress concentration effects. This study presents a hybrid computational approach that combines an irregular finite element mesh for stress–strain analysis with a regular mesh for efficient stimulus calculation. Stress and strain energy density values are transferred between the two domains using transformation matrices. Bone remodelling is simulated using the adapted Huiskes–Weinans. The method was demonstrated on a two-dimensional model of trabecular and cortical bone surrounding a cranial fixator screw. Results show that the proposed approach significantly reduces computational time while preserving biologically relevant stimulus evaluation and expected remodelling behaviour. The method provides an efficient and accurate alternative for large-scale bone remodelling simulations.
