- | It is now possible to impose a periodic solicitation by giving only points on the firstperiod (t in [0, T]). For each step, Lagamine calculates the phase as a function of time and frequency FREQ, then reads the corresponding entry in the .loa or .dep file (according to IPRES value). \\ | + | It is now possible to impose a periodic solicitation by giving only points on the first period (t in [0, T]).

|Time| Definition moment of the imposed values. This moment is compared to the accumulated time, sum of the DELTAT given in the command file. A linear interpolation is realized if a computation step is situated between two definition moments. | | |Time| Definition moment of the imposed values.
