A new method combining the finite cell method with the Fischer-Burmeister-Newton-Schur algorithm (FCM-FBNS) was developed to solve the multiscale problem of modeling surface texture with mass-conserving cavitation. Numerical experiments showed that FCM-FBNS has strong robustness and high computational efficiency. It is suitable for parallel processing and has a flexible meshing strategy for complex geometries.
To solve the multiscale problem of modelling surface texture with mass-conserving cavitation, a new method combining the finite cell method with the Fischer-Burmeister-Newton-Schur algorithm (FCM-FBNS) was developed. Numerical experiments confirmed that the proposed method has strong robustness and a high computational efficiency. When the number of degrees of freedom (DOFs) was 360,000, the calculation difference between FCM-FBNS and the finite-element method (FEM) was < 1 %, and the computation time was approximately 1 % of that of the FEM. FCM-FBNS is suitable for parallel processing, and the computation time increases nearly linearly with an increase in the number of DOFs in most cases. Furthermore, FCM-FBNS has a flexible meshing strategy for discretising complex geometries.
