Frevo
Frevo is probably the simplest tool for evolutionary design
FREVO is an open-source framework developed in Java to help engineers and scientists in evolutionary design or optimization tasks. The major feature of FREVO is the componentwise decomposition and separation of the key building blocks for each optimization tasks. We identify these as the problem definition, solution representation and the optimization method. This structure enables the components to be designed separately allowing the user to easily swap and evaluate different configurations and methods or to connect an external simulation tool. The latest version in development is hosted at https://github.com/smartgrids-aau/Frevo -

...It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

The FMI++ Library
A High-level Utility Package for FMI-based Software Development
...On the other hand, such a low-level approach implies several prerequisites a simulation tool has to fulfill in order to be able to utilize such an FMI component. The FMI++ library addresses this problem for models and tools with interfaces according to the FMI specification by providing high-level functionalities, which ease the handling and manipulation of such models and tools. Furthermore, the FMI++ library provides utilities to implement FMI-compliant interfaces for a large class of simulation tools. The FMI++ library intends to bridge the gap between the basic FMI specifications and the typical requirements of simulation tools. ... -

Python/FEniCS Examples
phase-field simulation and other examples with Python/FEniCS
The main goal of this project was developing phase-field simulations of lithium dendrite growth with FEniCS programmed in Python. The problem was based in the grand potential-based model of Zijian Hong and Venkatasubramanian Viswanathan (https://doi.org/10.1021/acsenergylett.8b01009) . Some simpler examples were developed before for a first approach with FEniCS: heat equation and combustion model. -

RTC-simulator
Simulation and Control of Processing Plants
...The simulations include a number of the techniques described in Applied Process Control – Essential Methods, and that book’s accompanying volume, Applied Process Control – Efficient Problem Solving. Actually, RTC is not merely a suite of simulations: Each application can be switched from “MODEL” to “PLANT” mode for real-time control of equipment through a somewhat basic interfacing arrangement. In “MODEL” mode, time can be accelerated or frozen. -

RAtom
solves nonlinear Kohn-Sham equation for the neutral atom.
RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from LAPACK libraries. The program is implemented in C++, it runs as a single thread. ... -

LIME
LIME is a software tool for creating multiphysics simulation codes.
...LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve di fferent parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defi ned approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code. To achieve its flexible lightweight design objectives, LIME 1.0 requires that some amount of customized software be written each time a new multiphysics application is created. ... -
