We present a new software project aimed at development of a novel and unique software environment, suited and capable of solving a wide set of X-ray FEL optics problems. The complex of programs is based upon libraries of the Synchrotron Radiation Workshop (SRW) package. The software can be used by XFEL experimental groups for developing scientific instruments, planning experiments and processing experimental data. Specific examples of applications of FEL wavefront propagation simulations are presented: modeling of edge radiation at the soft X-ray FEL facility FLASH and of the wavefront propagation through grazing incidence optics of the hard X-ray beamlines of the European XFEL 1. Possible ways for parallelization of calculations are also discussed.
