The article is devoted to the development of models of felt materials used in armor by numerical methods. To create a finite element mesh of felt material software in C++ was developed, designed, implemented and tested. The software allows you to create numerical models of felt material with straight fibers or twisted fibers with a broken line. Models of felt materials are created, conducted supercomputer simulations of impact loading felt material in the software LS-DYNA and compared with experimental data. Work is devoted to the development a system to create a computer models of felts, which are used in armor. The system was designed and implemented. System testing was performed. This system allows to create models of felts with the straight fibers or with the curved fibers in a broken line. The resulting models are designed for the supercomputer simulation shock loading of felts in the framework of the LS-DYNA software package.
