Embed one’s own physical property database

The method for Aspen to incorporate its own property databases is as follows: 1. Requirements for data file format – Custom property data supported by Aspen are usually provided in plain text (ASCII) file format, with extensions typically being“.inp” or“.dat”. - The data in the file must be defined according to the syntax specified by Aspen: including the exact name of the substance, CAS number, names of physical property parameters, values, units, and relevant equations. These formats are described in detail in the Aspen help documentation. II. Data Embedding Methods 1. In Aspen Properties, select the “User Defined” user-defined module ； 2. Create a new custom property database or open an existing one ； 3. Import or manually enter physical property parameters (the aforementioned text file can be imported) ； 4. After verifying the data and saving it, associate it with your process model to enable its use in process simulation. For specific operations, refer to the “User-defined Property Data” section in Aspen’s official user guide. .

For custom property data supported by Aspen, the data in the file must follow the syntax specified by Aspen. Are there any grammar explanations, or examples you’ve done before? Thank you!
