A new multiscale computational strategy was introduced recently for the analysis of structures. It involves an automatic homogenization procedure in space and in time. This procedure requires the resolution of a large number of linear evolution equations. Here, we present a robust approximate resolution technique for these equations, based on the concept of radial approximation. It leads to the construction of a relevant reduced basis of space functions and it is particularly suitable for the analysis of composite structures.
