Predict and eliminate porosity, shrinkage, misruns, cracks, and warpage before the first mold is poured. Optimize gating and feeding, cut material waste, and validate designs faster with physics-accurate simulation.














PoligonSoft is an all-in-one Casting Simulation Software based on the Finite Element Method (FEM). The system integrates three physics solvers for comprehensive analysis of casting processes:
Hydrodynamic Analysis: Models mold filling dynamics to predict flow patterns, identify potential mold erosion zones, and detect possible misruns.
Thermal Analysis: Simulates heat transfer during solidification and cooling phases to predict shrinkage porosity formation and optimize gating/feeding systems.
Stress Analysis: Computes thermo-mechanical stresses and strains to evaluate hot tearing susceptibility, residual stresses, and dimensional stability.
The integrated solver architecture enables simulation of conventional and specialized casting processes, providing quantitative data for process optimization and defect prevention throughout the entire production cycle.

Analyze and resolve the root causes of defects in the design phase
Visualize and control every stage in your casting process
Replace slow and expensive physical trials with virtual prototyping

Ultimately, The Midnight Library advances a quiet, radical form of existential humanism. Nora’s rescue does not come from finding the “best” possible life, but from realizing that the desire to escape choice is itself a form of death. The librarian, Mrs. Elm, who guides Nora, represents the voice of grounded wisdom: she never tells Nora what to do, but instead teaches her how to read the books—that is, how to interpret her own regrets. When Nora finally returns to her original life, it is not because that life has changed, but because she has. The same flat, her same brother’s distance, the same abandoned career—none of these are magically resolved. What changes is Nora’s relationship to them. She chooses to live not because life is perfect, but because it is hers . In this way, Haig offers a profound rebuttal to the tyranny of infinite possibility: freedom is not having every door open, but choosing one door and walking through it with open eyes.
The library itself serves as a crucial metaphor for the human mind’s obsession with counterfactuals—the “what ifs” that haunt every decision. Initially, Nora sees the library as a salvation, a way to escape the life she believes she has ruined. Her root problem, however, is not her circumstances but her perspective. She suffers from what philosopher Soren Kierkegaard called “the dizziness of freedom”—the anxiety that arises from infinite possibility. In each alternate life—whether as a glaciologist in Svalbard, a rock star’s girlfriend, or an Olympic swimmer—Nora discovers that new successes bring new, unforeseen sorrows. The life of a famous musician comes with betrayal and loneliness; the life of a loving wife and mother arrives with the grief of losing a spouse. Haig masterfully illustrates that no existence is free of pain. The library’s lesson is humbling: regret is not a sign that we have chosen wrongly, but an inherent feature of being human.

Matt Haig’s The Midnight Library (2020) has resonated with millions of readers worldwide, not merely as a work of speculative fiction, but as a philosophical meditation on regret, choice, and the meaning of a life well-lived. The novel follows Nora Seed, a woman in her thirties who, after a series of perceived failures, attempts suicide and finds herself in a mystical library between life and death. Each book on the library’s shelves offers her the chance to undo a past regret and live an alternate version of her life. Through this inventive narrative device, Haig constructs a powerful argument: the relentless pursuit of a “perfect” life is not only futile but also a barrier to genuine contentment. By examining Nora’s journey through the Midnight Library, one can see that Haig’s central thesis is not that life has infinite potential, but that meaning is found in accepting limitation, embracing imperfection, and committing to the messy, singular reality of one’s own existence. Ultimately, The Midnight Library advances a quiet, radical
Furthermore, Haig challenges the modern, Western cult of “potential”—the idea that we are defined by what we could become rather than what we are . Each time Nora enters a new life, she finds herself lacking the accumulated wisdom and emotional context of the life she left behind. She cannot simply transplant her consciousness into a different timeline and expect happiness; the relationships, achievements, and identities in those lives belong to a version of herself that she did not become. This subtle narrative point dismantles the fantasy of the “do-over.” The book argues that our identities are not a collection of interchangeable outcomes, but a cohesive narrative shaped by the very regrets we wish to erase. Nora’s beloved father, for instance, still dies in most timelines; her cat, Voltaire, is only truly hers in her original life. These small, heartbreaking constants force Nora—and the reader—to recognize that grief and loss are not obstacles to a good life, but its unavoidable textures. Elm, who guides Nora, represents the voice of



The first version of the PoligonSoft casting simulation software, initially named SAM LP 'Poligon,' was developed in 1989 at the Central Research Institute of Materials (CIM, St. Petersburg) by order of the Ministry of Defense Industry.
It was the world's first commercial software package to implement a mathematical model for calculating microporosity. PoligonSoft has since been successfully adopted by aerospace industry enterprises, where stringent casting quality standards are required.
For over 30 years, the casting simulation software has continuously evolved, integrating extensive expertise and knowledge from leading institutes and numerous companies in Russia and abroad.
In July 2009, the PoligonSoft development team joined CSoft Development.
