TASEF is a finite element computer program for the analysis of temperature distribution in sections which are exposed to fire or other sources of high temperatures.


TASEF handles plane or axi-symmetric cross-sections.  TASEF uses the finite element method for thermal analysis in two dimensions.  The meshing of the cross-section is shown by a graphical interface.  Cut outs and voids can be incorporated in the section geometry.


Certain standard fires are built into TASEFplus including ISO 834, EN 1363-1 and ASTM E-119.  There is a facility to adopt Eurocode parametric fires.  Completely customised fires can also be specified.  The user specifies the times at which the temperature output is desired.  The program can handle several fires for various boundaries of the cross-section. These include typical fires defined by time temperature curves, incident heat flux by radiation combined with convection heat transfer from adjacent gases, boundaries with prescribed temperatures that may follow a specified fire curve, as well as ambient non-fire boundaries. A special feature is the possibility to model heat transfer by radiation and convection in voids.


Thermal material properties like conductivity and specific volumetric enthalpy (density and specific heat capacity) can vary with temperature and latent heat due to water evaporation can be modelled.  Properties of steel and concrete based on Eurocodes 2-4 are built into the input generator TASEFplus.  Completely customised material properties can also be defined.


TASEFplus has the facility to view colour contours for calculated temperature distributions. In addition, a completely annotated text file output is generated.


TASEFplus including TASEF is supplied with a detailed User Manual and Example Manuals in which the user is guided step-by-step through specific problems.
