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

The Intersection of the Transgender Community and LGBTQ+ Culture
The world will tell you that to change is to lie. But you know the opposite is true: to refuse change is to live a beautiful lie. To change, to grow, to shed, to reclaim, to transition—that is the honesty of all living things. The caterpillar does not apologize to the twig for becoming wings. The snake does not mourn the skin it leaves behind in the grass. And you—you are not betraying your past. You are fulfilling its deepest hope: that you would one day become fully, fiercely, tenderly you .
The transgender community has profoundly shaped global pop culture, language, and art. Much of modern slang, fashion, and performance styles originated within the Black and Latine transgender and queer ballroom subcultures of the late 20th century.
A transgender person can identify as straight, gay, lesbian, bisexual, asexual, or pansexual. Solidarity and Friction

The evolution of LGBTQ+ culture is inseparable from the history and resilience of the transgender community. By honoring past pioneers, protecting vulnerable members, and celebrating authentic self-expression, the collective movement moves closer to a world where everyone can live safely and openly.

Houses functioned as intentional, alternative families for queer and trans youth rejected by their biological relatives. Led by a House "Mother" or "Father" (frequently experienced trans women or men), these structures provided mentorship, shelter, and a sense of belonging. Cultural Exports

The relationship between the transgender community and LGBTQ+ culture is symbiotic. The trans community helped build the infrastructure, language, and spirit of resistance that defines modern queer life. In return, the collective power of the LGBTQ+ coalition provides a vital platform for trans advocacy, safety, and celebration. As culture continues to evolve, the voices of trans individuals remain essential to pushing the boundaries of what it means to live authentically.
Activists like Marsha P. Johnson, a Black trans woman, and Sylvia Rivera, a Latina trans woman, were not just participants but leaders in the uprising and the movement it inspired. Together, they later co-founded the Street Transvestite Action Revolutionaries (STAR) to provide housing and support for homeless queer and trans youth, particularly those who were most marginalized. Despite their foundational role, the contributions of Johnson and Rivera and other trans activists were sidelined and erased from mainstream retellings for decades, a process that often prioritized the narratives of more assimilationist white gay men over the radical, intersectional voices at the movement's core.
Much of what the world currently recognizes as mainstream LGBTQ+ culture—including slang, fashion, dance, and humor—originates directly from the historical trans and gender-nonconforming community, specifically Black and Latine trans individuals within the ballroom scene.
The underground drag balls of Harlem in the 1960s-80s, immortalized in the documentary Paris is Burning , were trans-centric. Categories like "Butch Queen Realness" and "Face" were dominated by trans women and gay men of color. The entire mainstream "voguing" craze, the vernacular of "shade," "reading," and "throwing the first stone"—all of it originates from a culture where trans femmes were the royalty.

The transgender community is diverse, resilient, and beautiful. Being part of LGBTQ+ culture means honoring a legacy of courage—the courage to live authentically in a world that doesn’t always understand. Inclusion isn’t about perfection; it’s about listening, learning, and showing up.
Key riots against police harassment, such as the Cooper Donuts Riot (1959) and Compton’s Cafeteria Riot (1966) , were led by trans people and drag queens years before the Stonewall Riots of 1969.
Despite facing relentless political and social headwinds, the transgender community has made indelible contributions to LGBTQ culture, particularly in the arts. Film and television have been a critical arena for visibility. The 2024-2025 television season saw a total of 489 LGBTQ regular or recurring characters on scripted broadcast, cable, and streaming platforms, a 4% increase from the prior year. Of these, 33 characters (6.7%) were transgender, marking an increase of nine characters.



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.
