Czech Society for Mechanics and Institute of Theoretical and Applied
Mechanics, CAS, invite you to a lecture and discussion within the lecture series ITAM Seminar
Solution of the multi-dimensional Fokker-Planck equation by means
of Finite Element Method
given by
Ing. Jiří Náprstek, Dr.Sc.
Institute of Theoretical and Applied Mechanics, CAS.
Fokker–Planck equation is one of the most important tools for investigation of dynamic
systems under random excitation. Finite Element Method represents very effective solution
possibility particularly when transition processes are investigated or more detailed solution is
needed. However, a number of specific problems must be overcome. They follow predominantly from the
large multi-dimensionality of the Fokker–Planck equation, shape of the definition domain and usual
requirements on the nature of the solution which are out of a conventional practice of the Finite
Element employment. Unlike earlier studies it is coming to light that multi-dimensional simplex
elements are the most suitable to be deployed. Moreover, new original algorithms for the
multi-dimensional mesh generating were developed as well as original procedure of the governing
differential and algebraic systems assembling and subsequent analysis. Finally, an illustrative
example is presented together with aspects typical for the problem with large
multi-dimensionality.
The team lead by dr. Náprstek received this year's Award of the CAS for outstanding results of great scientific significance for research conducted on the topic of the announced lecture.
The lecture will be held on Wednesday, December 12, 2018 at 10:00 AM in the building of the
Institute of Theoretical and Applied Mechanics, Prosecká 76, 190 00, Prague 9
