PhimecaSoft is an uncertainty treatment software based on OpenTURNS. It is couple-able with any calculation code and permits to spread, quantify and order the uncertainties.


The computer analysis of physical phenomenon is often realized by using deterministic data coming from expertise or counterbalanced by safety coefficients. However, despite these precautions, zero risk does not exist and the penalty caused by the safety coefficients can be expensive. The natural variability prevents any perfect knowledge. The need to reflect this is, so, unavoidable to optimize the reliability of a structure without destroying its cost of construction/maintenance.

PhimecaSoft allows to introduce the risk concept in each physical problematic. In this way the analysis is not deterministic anymore but stochastic. Strong in its graphical multi-platform interface, PhimecaSoft is simple to use. The software organization follow the scheme in 4 treatment of uncertainties phases :

  • Physical modeling of the problematic,
  • Probabilistic modeling of the input data,
  • Propagation of uncertainties for the sensitivity or reliability analysis,
  • Determination of the input data influence on the on-put result.
