Our technical computation experts perform demanding strength and vibration analyzes, flow computation, structural physics computational tasks, load-bearing structure optimization, and other computational tasks in product development and research.<\/p>\n

With modern tools, different constructions can be easily compared to find a suitable alternative. Simulations can also be used to study phenomena and situations that would otherwise be impossible or too expensive to examine. We are pioneers in the optimization of load-bearing structures, which is a natural extension of computer-aided simulation of structures. The optimization is not satisfied with the comparison of the existing plans, but new and better constructions are produced.<\/p>\n

Our services include dynamic examinations, load cell optimization, strength calculations<\/a> and FEM analyzes, seismic analyzes, fire calculations, building physics examinations, stability examinations, computational fluid dynamics calculation (CFD)<\/a> and various simulations.<\/p>\n<\/p>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\n \t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n\n\n

Simulations and analyzes of structures help to avoid risks and save time and money. They otherwise replace or reduce the number of tests required.<\/p>\n

As a simulation tool, we typically utilize FEM (finite element method) and flow calculation (CFD).<\/p>\n

The simulation targets related to the structures are:<\/p>\n

    \n
  1. Collision simulation and dimensions, which are used to assess e.g. the impact of vehicles on structures<\/li>\n
  2. Explosion simulation to study the behavior of structures in different accident situations<\/li>\n
  3. Thermal simulation of concrete structures evaluates the heating needs of the structures under different conditions<\/li>\n
  4. Wind simulations for structures<\/li>\n
  5. Flow water simulations for structures<\/li>\n<\/ol>\n

    The most typical analyzes of structures:<\/p>\n

      \n
    1. Requires nonlinear strength analyzes that are utilized in situations where conventional sizing formulas are not sufficient.<\/li>\n
    2. Dynamic dimensioning of structures used to identify vibrations in structures caused by equipment, wind and walking.<\/li>\n
    3. Seismic sizing and analyzes to ensure the durability of structures located in earthquake zones.<\/li>\n
    4. Fatigue measurement is utilized to examine the fatigue of dynamically loaded steel structures.<\/li>\n<\/ol>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n\n\n
