Abstract In this two‐part paper, we present a collection of numerical methods combined into single framework, which has the potential for successful application to wind turbine rotor modeling and simulation. Part 1 paper focus on: 1. The basics geometry analysis‐suitable construction rotors; 2. fluid mechanics formulation its suitability accuracy rotating turbulent flows; 3. coupling air flow rigid body. 2, on structural discretization blades details fluid–structure interaction computational...
This paper provides a detailed elaboration and assessment of the most common domain decomposition methods for their application in isogeometric analysis. The comprise penalty approach, Lagrange multiplier methods, Nitsche-type method. For Nitsche method, new stabilized formulation is developed context analysis to guarantee coercivity. All these are investigated on problems linear elasticity eigenfrequency 2D. In particular, focus put non-uniform rational B-spline patches which join...
Abstract We introduce a novel hybrid methodology that combines classical finite element methods (FEM) with neural networks to create well-performing and generalizable surrogate model for forward inverse problems. The residual from custom loss functions are merged form the algorithm. Finite Element Method-enhanced Neural Network (FEM-NN hybrid) is data-efficient physics-conforming. proposed can be used models in real-time simulation, uncertainty quantification, optimization case of It update...
SUMMARY Co‐simulation is a prominent method to solve multi‐physics problems. Multi‐physics simulations using co‐simulation approach have an intrinsic advantage. They allow well‐established and specialized simulation tools for different fields signals be combined reused with minor adaptations in contrast the monolithic approach. However, partitioned treatment of coupled system poses drawback stability accuracy challenges. If several subsystems are used form scenario, these issues especially...
This work presents a novel application of the Shifted Boundary Method (SBM) within Isogeometric Analysis (IGA) framework, applying it to two-dimensional and three-dimensional Poisson problems with Dirichlet Neumann boundary conditions. The SBM condition imposition is achieved by means fully penalty-free formulation, eliminating need for penalty calibration. numerical experiments demonstrate how order elevation, coupled through higher-order Taylor expansions, consistently achieves optimal...
In this paper we present the updated reference strategy for numerical form finding of pre-stressed membranes, which is based on standard finite element discretization. The singularities inverse problem are regularized by a homotopy mapping. A projection scheme proposed where anisotropic pre-stress defined with respect to an additional plane, reflects initially developable surface membrane strips in production process. Physically problematic combinations edge geometry and stress solved...
The present paper is the numerical counterpart of a recently published experimental investigation by Wood et al. (2018). Both studies aim at instantaneous fluid–structure interaction (FSI) phenomena observed for an air-inflated flexible membrane exposed to turbulent boundary layer, but looking coupled system based on different methodologies. objective supplement investigations additional insights, which were impossible achieve in experiments. Relying large-eddy simulation technique...
