Office in Kolkata
CSoft Development Private Limited works to strengthen the availability, adoption, implementation, technical understanding, and support of CSoft technologies throughout India.
We connect globally developed engineering technologies with the requirements of Indian manufacturers, foundries, engineering companies, consultants, research institutions, educational organizations, designers, and industrial enterprises.
Our approach
Technology should solve real engineering problems. Software is valuable not merely because of its features, but because of the measurable improvements it can create in engineering accuracy, product quality, production efficiency, development time, resource utilization, and decision-making.
Global Engineering Technology with a Strong Indian Presence
CSoft develops professional engineering technologies focused on accuracy, reliability, interoperability, and efficient management of complex technical information. Its solutions support the engineering lifecycle, including concept development, digital design, analysis, simulation, manufacturing, construction documentation, product data management, and technical information processing.
In India, CSoft Development Private Limited operates from Salt Lake Sector V, Kolkata, providing local access to advanced engineering software, technical assistance, training, implementation support, product guidance, and specialized expertise. CSoft believes successful software implementation goes beyond installation. Solutions must fit each organization’s workflows, standards, tools, challenges, capabilities, and long-term objectives. This customer-focused approach drives CSoft’s work in the Indian market.
PoligonSoft – Advanced Casting Simulation from CSoft
One of CSoft’s flagship engineering technologies is PoligonSoft, a professional metal casting simulation system designed for foundries, casting engineers, metallurgists, researchers, and manufacturing organizations. It is an all-in-one casting process simulation environment based on the Finite Element Method (FEM), integrating hydrodynamic, thermal, and stress analysis to help engineers evaluate casting behavior before production.
Instead of relying mainly on physical trial-and-error, foundries can use PoligonSoft to virtually evaluate process conditions, compare configurations, identify potential defects, optimize gating and feeding systems, study solidification, and understand thermo-mechanical behavior. This enables engineers to detect potential production problems while casting technology is still being designed.
Analyze the complete casting process—not just one isolated stage.
Casting quality depends on the interaction of many events throughout production. Mold preparation affects filling, filling affects temperature distribution, and temperature influences solidification. These stages directly impact shrinkage, porosity, stress, deformation, and cracking, while cooling and subsequent manufacturing operations can introduce further changes.
PoligonSoft is designed to simulate these successive stages as a connected technological process rather than as separate calculations. Engineers can model the process from mold conditions and molten-metal filling through cooling and solidification, extending to later operations such as casting removal and cutting of feeding systems and risers. This end-to-end approach provides greater visibility into how production decisions at one stage can influence casting quality and performance at later stages.
Advanced Physics for Real Foundry Challenges
PoligonSoft combines specialized computational technologies to help engineers investigate the physical phenomena responsible for casting quality.
Hydrodynamic Analysis: PoligonSoft simulates molten-metal flow through the gating system and mold cavity, helping engineers assess filling dynamics, velocity, temperature, free-surface behavior, early solidification, and risks of incomplete filling or misruns.
Thermal and Solidification Analysis: PoligonSoft analyzes heat transfer and solidification through conduction, convection, radiation, and phase transformation. Engineers can identify temperature fields, hot spots, shrinkage cavities, macro- and microporosity, and potential feeding issues.
Stress and Strain Analysis:
PoligonSoft evaluates thermo-mechanical behavior during cooling, considering thermal gradients, shrinkage, mold interaction, and material behavior. It helps investigate plastic strain, residual stresses, cracking risks, and dimensional stability.
Simulation Across Multiple Casting Technologies
Modern foundries use diverse manufacturing processes, materials, molds, operating conditions, and equipment, requiring simulation software that can adapt to different production environments.
Casting Process Support: PoligonSoft supports a wide range of conventional and specialized casting technologies, including sand casting, investment casting, lost-foam casting, vacuum casting, die casting, centrifugal casting, continuous casting, heat-treatment analysis, and macrostructure simulation.
Geometry and Materials: The system handles complex casting and mold geometries with cores, chills, sand or ceramic molds, insulating and exothermic materials, and other technological elements that affect casting behavior. This versatility makes PoligonSoft suitable for diverse industries and casting applications.
From CAD Geometry to Engineering Decisions
Effective casting simulation begins with accurate digital representation of the product and manufacturing environment. PoligonSoft includes capabilities for converting CAD geometry into finite-element models composed
of tetrahedral elements. The technology supports engineering workflows involving widely used CAD and CAE data and provides tools for mesh generation, mesh-quality optimization, surface creation, process preparation,
material definition, boundary-condition setup, and reusable calculation templates.
For investment casting applications, PoligonSoft also provides technology for generating ceramic-shell finite-element geometry based on the surface of the wax model, reducing the need to construct the complete
shell manually in CAD before simulation.
The goal is not simply to produce attractive simulation images. The goal is to transform engineering data into actionable manufacturing decisions
Predict Problems Before They Reach Production
Physical casting trials consume materials, time, energy, and production resources. Simulation moves much of this investigation into the digital environment, reducing the need for costly physical trials.
By virtually evaluating a process before production, foundries can investigate conditions associated with:
PoligonSoft helps reduce scrap and rework, improve process control, and accelerate product development through virtual engineering analysis. For modern foundries, it provides a practical advantage in improving quality while controlling production costs.
Supporting Indian Foundries and Manufacturing Industries
India has a diverse manufacturing ecosystem, from small and medium-sized foundries to major automotive, engineering, railway, defence, energy, aerospace, machinery, pump, valve, and infrastructure industries. As competition grows, manufacturers face increasing pressure to improve quality while reducing development time, scrap, energy, material usage, and physical trials.
CSoft Development Private Limited supports India’s shift toward simulation-driven manufacturing by making PoligonSoft available with product information, technical resources, implementation assistance, training, and professional support. Through channel partners, CSoft also expands access across the country. Its goal is to help organizations build the knowledge needed to make simulation an effective part of engineering and production strategies.

At CSoft Development Private Limited, we believe that the future of engineering will be defined by the intelligent integration of design, simulation, digital information, automation, and manufacturing knowledge.
Engineering organizations should be able to investigate ideas digitally before committing expensive physical resources. Manufacturers should be able to identify risks before defects appear on the production
floor. Designers should have better visibility into manufacturing consequences. Engineering knowledge should be captured, reused, and continuously improved. Our role is to help make these capabilities
practical and accessible. Whether through casting simulation with PoligonSoft or through the broader CSoft portfolio of CAD, BIM, PLM, engineering, design, documentation, and digitalization technologies,
our mission remains consistent:
to give engineers better tools for solving complex real-world problems. We combine international technology with local accessibility, technical knowledge with practical engineering experience,
and sophisticated software with a commitment to customer success.
