    Abstract: The advance in computer modeling techniques observed in last decades allows for creating so-called computer twins in variety of real-world applications. One of the well-developed technique that found to be extremely useful in variety of acoustic areas is based on using Finite Element Method and Boundary Element Method. Both has been already commercialized in the form of advanced software packages that facilitate verification of whole designs.\n \nHowever in many research areas a ready to use commercial software are still not prepared for research calculations. Hence the idea of using programmable methods that allows for the insight into internal workings of the computer model with a usage of a methods dedicated for Finite/Boundary Element approach. Among many of long-developed open-source packages is FreeFEM++ that is characterized by maturity in implementing of sophisticated numerical algorithms and giving higher abstraction level in software programming than modern object oriented languages.\n \nTo illustrate the proposed idea the modeling of fish target strength is presented. The examples are mainly oriented for using it in statistical calculation of target strength vs. fish length relation.
