This paper describes the format of material data files that hold parameters needed by thermal and hygrothermal simulation tools such as Delphin, Hajawee (Dynamic Room Model) and Nandrad. The Material Data Files are containers for storing parameters and functions for heat and moisture transport and storage models. The article also discusses the application programming interface of the Material library that can be used to read/write material data files conveniently and efficiently.:1 Introduction 2 Magic Headers 3 File Name Conventions 4 Format Description 4.1 String/Identifier Value Type 4.2 Internationalized/Translated String Value Type 4.3 Parameter Value Type 4.4 Special Data Lines and End-of-File Convention 4.5 Special Keyword FUNCTION 5 Material File Sections 5.1 Section Keywords 5.2 Completeness of Material Data 5.3 Section [IDENTIFICATION] 5.4 Section [STORAGE_BASE_PARAMETERS] 5.5 Section [TRANSPORT_BASE_PARAMETERS] 5.6 Section [MECHANICAL_BASE_PARAMETERS] 5.7 Section [MOISTURE_STORAGE] 5.8 Section [MOISTURE_TRANSPORT] 5.9 Section [HEAT_TRANSPORT] 5.10 Section [AIR_TRANSPORT]

Abstract This paper describes the file formats of the output data and geometry files generated by the Delphin program, a simulation model for hygrothermal transport in porous media. The output data format is suitable for any kind of simulation output generated by transient transport simulation models. Implementing support for the Delphin output format enables use of the advanced post-processing functionality provided by the Delphin post-processing tool and its dedicated physical analysis functionality.:1 Introduction 2 Magic Headers 2.1 Version Number Encoding in Binary Files 2.2 Version Number Encoding in ASCII Files 3 Output Data File Format 3.1 File Name Specification 3.2 General File Layout 3.3 ASCII Format 3.4 Binary File Format 4 Geometry File 4.1 General 4.2 File Name Specification 4.3 ASCII Format 4.4 Binary Format 5 Summary A Changes
