СКМ ЛП ПолигонСофт Критерий-3D is a specialized module for criterion-based analysis of casting simulation results. It is used to evaluate process factors and casting properties based on previously calculated temperature, time, cooling rate, and other parameter fields.

In official CSoft Development materials, the module is also referred to as Критерий. Its capabilities are described on the current POLIGONSOFT website.

Simulation Result Analysis

Criterion-based analysis calculates additional indicators using thermal and other simulation results. This helps identify casting areas that require the process engineer's attention.

• Calculate local cooling rates.
• Analyze material microstructure formation conditions.
• Evaluate hardness-related parameters.
• Assess susceptibility to burn-on and mold erosion.
• Analyze the spatial distribution of criteria.

Criteria can be applied to a selected area of the simulation model and displayed as value fields.

Niyama Criterion

One established application of the module is calculating the Niyama criterion. It accounts for local thermal conditions during solidification and is used to assess susceptibility to shrinkage porosity.

The resulting value map allows users to compare areas of potential defects with results from POLIGONSOFT's specialized porosity model.

Custom Criteria

Критерий-3D supports the creation of custom calculation expressions. A set of mathematical functions and operations is available for this purpose.

Supported operations include powers, logarithms, trigonometric functions, gradients, rates of change, and searches for minimum and maximum values.

This allows engineers to adapt the analysis to the specific casting process and use indicators established at a particular production facility.

Use in POLIGONSOFT

The module requires results from preliminary calculations. Input fields are generated by the corresponding POLIGONSOFT solvers.

Engineers analyze the distribution of criteria in the 3D model, create sections, and compare calculated values for different process configurations.

СКМ ЛП ПолигонСофт Расчет теплоизлучения is an additional POLIGONSOFT calculation module for simulating radiative heat transfer between the surfaces of a casting, its mold, and surrounding equipment.

It is used to design casting processes in which thermal radiation significantly affects temperature distribution. It is particularly useful for vacuum casting and the production of critical investment castings.

Radiative Heat Transfer

Unlike simplified thermal models, the module accounts for the geometric arrangement of surfaces and their interaction through thermal radiation.

• Calculate radiative heat transfer between surfaces.
• Account for mutual shadowing of structural components.
• Simulate re-radiation.
• Analyze interactions between castings, molds, and equipment.
• Determine the effects of radiation on temperature fields.

Calculations use a finite element model with specified surface properties and thermal conditions.

Applications in Vacuum Casting

The module is used to simulate manufacturing processes in which radiation is a significant heat transfer mechanism.

For example, during vacuum investment casting, the arrangement of casting cluster components and equipment affects the cooling intensity of individual areas.

Calculations make it possible to evaluate changes in temperature distribution when castings, molds, and heating elements are arranged differently.

Calculation Preparation

POLIGONSOFT uses the Трассировка preprocessor to prepare radiative heat transfer calculations. It determines the mutual visibility of surfaces in the finite element model.

The resulting data is then used by the thermal solver when simulating cooling and solidification.

POLIGONSOFT 2025 introduced the ability to reuse a previously prepared ray-tracing file when the mesh and boundary indices remain unchanged.

This eliminates the need to prepare the same data again for successive calculations using one geometric model.

Results and Compatibility

Analysis results are displayed as temperature fields, cross-sections, and temperature variation charts. They can be used to compare process alternatives and evaluate the conditions under which defects may form.

The module operates as part of POLIGONSOFT. It is not a standalone application for casting process design.

CAD.kz can help confirm module compatibility and select a configuration for casting process simulation.

СКМ ЛП ПолигонСофт Центробежное литье is an additional module for simulating casting processes involving mold rotation. It is used to develop centrifugal casting processes for metal castings, including complex components made from specialized alloys.

The module operates within POLIGONSOFT and uses its fluid dynamics and thermal calculation models while accounting for mold rotation.

Centrifugal Casting Simulation

Simulation inputs include casting assembly geometry, materials, temperature conditions, and mold rotation parameters.

The developer specifies the ability to define the rotation axis, direction, and speed. These parameters are used to simulate mold filling and subsequent metal solidification.

• Calculate filling of a rotating casting mold.
• Analyze molten metal flow during rotation.
• Simulate cooling and solidification.
• Predict shrinkage cavities and porosity.
• Analyze the effects of rotation parameters on results.

Mold Filling Analysis

When the appropriate solver is available, POLIGONSOFT simulates molten metal movement, temperature changes, and the characteristics of mold filling.

The resulting data allows engineers to investigate how the selected rotation speed and gate placement affect metal distribution.

Calculations also help assess the risk of incomplete filling in specific areas and changes in thermal conditions during pouring.

Solidification and Shrinkage Defects

POLIGONSOFT provides specialized models for predicting shrinkage macro- and microporosity in centrifugal casting.

Engineers can analyze temperature fields, areas where shrinkage cavities form, and porosity distribution while comparing results from different process conditions.

Official materials describe the software's use in centrifugal casting of titanium components into ceramic molds under vacuum.

Calculation Preparation and Results

POLIGONSOFT uses a finite element model of the casting and mold, material property libraries, and the Мастер preprocessor.

In versions based on the new architecture, rotation parameters are transferred through the JNL project file. The separate ROT file used previously is no longer required.

Results are available as 3D fields, sections, charts, and visualizations of filling and solidification processes.
