I am a precursor in Poland of modern computer simulation methods called isogeometric analysis . I started researching these methods in 2011 while working in an international team to determine the cost of making such simulations. It turned out then that the computer simulation methods used require very long computation times on large computers from supercomputing centers to obtain accurate simulations. Additionally, they require problem specific stabilization methods to obtain reliable simulation results. In the field of isogeometric analysis, I discovered a new, automatically stable, low-cost way to perform challenging computer simulations on a regular laptop. Recently, I am also researching using Deep Neural Networks in computational science.
