Altair Inspire PolyFoam 2021.2.0 release notes
Altair Inspire PolyFoam 2021.2 includes the following new features and enhancements.

Multi-Physical blowing agent (PBA)
The actual blowing process of rigid PU foam is the physical blowing process in which a low-boiling liquid incorporated in the reaction mix is vaporized due to the heat of the reaction. Various PBA is used together or alone for responding to global climate change and good properties such as low-temperature foaming and low thermal conductivity. Since only one type of PBA could be set in the previous version, a new feature was added to enable multiple PBAs for user convenience in this version.
Users can set the number of physical blowing agents in the Mixing ratio tab of Materials window like the figure below. Material properties such as density, specific heat, conductivity, boiling temperature, and molecular weight need to be input as many as the number of PBA.

Isocyanurate reaction (PIR)
Analysis results now include an isocyanurate reaction result type. Poly-isocyanurate (PIR) foam is recognized as the efficient thermoinsulations utilized for constructions. Manufacturing processes of PIR foams are like those of rigid polyurethane (PUR) foams . Isocyanurate linkages are formed by cyclotrimerization of excess isocyanate compounds using suitable trimerization catalysts. The outstanding properties of PIR foams are inherent thermal stability and low flammability.
PIR reaction can be described by the following formula. There is a very complex reaction mechanism, but a simplified reaction equation is used for modeling.

- A: Pre-exponential factor
- E: Activation energy of reaction
- dH: Heat of reaction
- Temperature: Reaction start temperature
- Order of reaction: Order of reaction in reaction kinetics (n)
Fluid critical gelling ratio
Fluid critical gelling ratio means the critical(limit) gelling ratio at which flow can occur. When the gelling ratio reaches this value, each element can no longer flow and does not foam, as if it had solidified. It is implemented for smooth rise at the final stage.

Additional Changes and Enhancements for Foaming
- Mesh Volume Change Warning: Inspire PolyFoam now calls attention to removed mesh volume. A relatively small element in which the voxel mesh is fragmented or separated from the product part is automatically deleted, and Inspire PolyFoam informs the user. Remeshing may be necessary if the volume removed is greater than 1%
.. If Removed Volume% == 0: Nothing is shown
.. If Removed Volume%
