Type98 enables the incorporation of CONTAM within the TRNSYS simulation environment ( and couple with Type56 to perform combined energy, airflow and contaminant transport simulations for multizone buildings. Type98 provides the continued benefit of the full features of CONTAM as it evolves without requiring a redevelopment of a new type as previously required with Type97. This coupling is enable using socket communications messages that are documented in the CONTAM User Guide. The Contam3dExport tool simplifies development of coupled models by extruding CONTAM projects drawn to scale using the pseudo-geometry mode of ContamW.

Example input files and References are provided below.

The table below indicates the compatibility between TRNSYS, Type 98, and ContamX.
