ASPEN is a widely used process simulator. ASPEN input files, typically denoted by the '.inp' suffix, are often used to store stream and physical property values. Cranium and Synapse can read and parse ASPEN input files, extracting physical property values into a knowledge base document.
The following is an example ASPEN input file (only the physical property information is displayed):
Values from the imported file are used to create chemicals and estimation techniques. Property values will be read into the newly created chemicals. Parameter values will be read into the newly created techniques.
Because new entities will be created, it is STRONGLY RECOMMENDED that you import values from an ASPEN input file into a template knowledge base. Only after you examine the imported values and verify their accuracy and completeness should you then import these values into your working knowledge base.
|Browse button for entering the name of the ASPEN input file to be imported.
|The entity type whose entities and properties are being displayed. ASPEN input files contain only chemicals and technique parameters.
|List of selected entities to be imported.
|The physical properties and attributes of the current entities to be imported.
|The Import Options control used to specify if imported values will be added, skipped or merged with existing values.
|The Import button begins the import process.
The application will read and parse the ASPEN input file collecting physical property values and estimation technique parameters. These values will then be written into the current knowledge base.
The following ASPEN input file contains properties and technique parameters for one chemical: 4-Ethylmorpholine. The accompanying knowledge contains the input file's contents.

|The knowledge base containing the property data and technique parameters imported from the accompanying ASPEN input file.
Please see our video demonstrating how to import an ASPEN input file into an MKS knowledge base.
The video demonstration imports the input file listed in the previous section creating the resulting knowledge base also listed in the previous section.
