Can the existing property data in Aspen be modified? How should it be modified

Can the existing property data in Aspen be modified? How should it be modified? For example, in the case of methanol, its physical properties in practical applications do not quite match those in Aspen; how should this be adjusted?
The material properties can be seen in setup-properties-parameters; just click on that property to make the changes directly
Data regression can be considered; the property values of pure components in Aspen are quite reliable. Regression of interaction parameters is commonly used, but pure components can also be utilized.
Yes, the data in ASPEN is still quite authoritative. Is the poster considering a heat transfer mechanics model?
3# How should data regression for laipi*ao*n be carried out? Is it necessary to conduct experiments? Could you be more specific? Provide a few methods
Additional question: It mainly involves changes to material property data, not just for pure components, but also more frequently in systems containing trace impurities. How should the data in Aspen be modified? Thank you to all the experts for their active participation
Physical property parameters of pure components or mixtures can be regressed using data regression, based on experimental data or literature data. For specific methods, please search within the forum or refer to the user manual
Physical properties can be modified; there are parameter fields under the \"Properties\" section. Generally, if no values are entered, Aspen will automatically use the properties from its built-in database. If the properties in that database do not suit the needs, one can enter their own properties. Curry’s physical properties can be derived and then entered under the “Parameters” section. Only modify parameters locally when making changes~
