Abstract: | In this paper, novel mesh techniques are proposed for wind field simulation of flexible spatial structure. For mesh generation,
an interpolation strategy is presented to obtain a mesh system with variable density. Two spatial structure examples are used
to examine the efficiency and applicability of this technique. Then based on the structured mesh system generated by the technique,
the mesh nodal coordinates are updated to adapt the moving boundary conditions by means of the mapping interpolation functions
and some examples are given to verify the effectiveness. Furthermore, the constrained counterforce distribution technique
and projection interpolation strategy are developed to implement the data exchange on the interaction surface of wind and
structure. Finally, the computational accuracy is numerically validated. |
