ThermXL is an add-in for Microsoft Excel, for performing simple thermal analysis within a spreadsheet. It provides an intuitive, easy-to-use thermal modelling environment perfect for conceptual studies, "What if...?" type analysis, etc.

ThermXL uses a lumped parameter approach and provides a structured interface for defining the network and associated control data, with optimised solvers for both steady-state and transient analyses.

The integration of ThermXL within Excel allows the full functionality of the spreadsheet to be used both for the model input definition and result presentation, providing enormous flexibility in model definition and greatly easing the model documentation, presentation and reporting.

• Full import of data from ESATAN-TMS Workbench
• Group capability including automatic heat flow calculation between groups
• Powerful analsyis control parameters for both steady state and transient solution
• Support for sensitivity analysis for design case study
• Interface to ThermNV for visualisation of the network
