SimuSol is free software for numerical simulation of physical circuits, with a focus on modeling thermal circuits, thermal systems, and solar energy devices. The main text clearly states that it consists of multiple Perl programs, uses Perl modules, and depends on a range of GPL free software to handle modeling, computation, and plotting workflows. It is more like a research- and education-oriented desktop toolchain than a modern SaaS developer platform.
Its core workflow is to describe circuits using Dia and the “thermal circuit” templates, run numerical simulations via Sceptre and Ngp, and then generate plots with Gnuplot or Simplot. The surrounding toolset is fairly extensive: Simplot can also be used independently as a 2D graphics description and plotting tool; Optimus is used for optimizing solar energy equipment; Radia generates synthetic solar radiation sequences; Tabular performs table interpolation and can interact with C, Fortran, and ExprTk; Psicro, Calcula, and Puyuspa are used to calculate properties such as humid air; and CSSAN provides capabilities related to the SimuSol project repository.
The main text indicates that SimuSol is GPL software, the site content is under the GNU Free Documentation License, and the software outputs are released under GPLv3 or AGPLv3. No commercial pricing is shown, so it can be regarded as free and open source. For installation, it supports Ubuntu 20.04/21.04 and mentions Windows 10, virtual machines, DEB/RPM packages, per-package source installation, and script-based installation of Dia-SimuSol. However, there are many components and dependencies, including Perl, Dia, Sceptre, and Gnuplot, making deployment more complex than modern one-click tools.
Its strengths are a clear focus and strong free-software positioning. It is well suited to users in solar energy, thermal engineering, research and teaching, and those who want an auditable toolchain. Its companion tools cover modeling, optimization, radiation data, interpolation, and psychrometric chart calculations. The downsides are that the website information appears dated, with news mainly from 2017–2021; the documentation is primarily in Spanish; the page structure is fairly fragmented; and there is no visible information about modern APIs, SDKs, cloud integrations, or commercial support, so ease of use is limited.
The main text does not provide information about China network access, mirrors, or payment options, so its accessibility from China can only be considered unknown. Since it is free and open source, there does not appear to be any payment barrier. If you need a more modern tool or a broader ecosystem, alternatives to consider depending on the use case include OpenModelica, EnergyPlus, TRNSYS, MATLAB/Simulink, and GNU Octave.
