• all types of parachutes and ballutes
• paragliders and hang-gliders
• balloons, blimps, airships
• inflatable shock absorbers
• automotive airbags
• air-supported and cable-supported constructions
• pneumo-panelled structures and pneumo-jacks
• shelters (passive and inflatable)
• tents
• sails
• inflatable figures and simulators
• flexible containers, fire buckets
• aircraft arresting units (nets and cords)

• current shape and velocity
• stressing state and deformations of shell reinforced by flexible carcass under loading
• reaction forces
• aerodynamic performances and flow around construction if structural code is coupled with aerodynamic one
• modeling 3D shapes and patterning
  
  

• Structural program MONSTR-2.2 based on modified finite-element method
Aerodynamic programs coupled with MONSTR-2.2:
• PARAD-2.2 based on Lagrange-Euler method for compressible fluid
• DVM-2 based on Discrete Vortices Method for low-speed flow
• EXPRESS based on original analytical method for high-speed decelerators
Patterning :
• PATTERNER-2.2 generates 2D pattern for any 3D detail
Each program has its own Preprocessor for fast and convenient data preparation, Processor for computing, and Postprocessor for multiwindow graphic analysis of results

• the structural code is applicable to any complex 3D construction and mesh up to 1.000.000 finite elements
• convenient and ergonomic 3D preprocessing and postprocessing
• fast computing (1 min. in test task for 20000 finite elements)
• good accuracy was confirmed in full-scale & model experiments, analytical solutions
• takes into consideration nonlinear behavior of materials, soft orthotropic fabric and flexible carcass
• huge deformation ~100% and displacement of construction are allowable
• dynamic solutions, reliable and fast convergence for static problems
• provides aeroelastic approach by coupling the structural and aerodynamic codes
• fast optimization of construction to choose the most suitable materials, position of carcass, shape (ex. equistressed, without wrinkles, smoothed), aerodynamic performances, etc.
