Sauna V4.5 New Features List
Random power profile, model with "raw data" control elements
New raw data control elements
 Use for random power data from experimental measurements or simulations
 Scripting is not required, input is from a tab or comma delineated
spreadsheet file
 No fixed limit on the number of steps, more than 1,000,000 steps possible
 Raw data types: wattage vs. time, boundary temperature vs. time
 For repeating and semirepeating data (square waves, ramps, etc.),
Sauna's scripted control elements can be used
 Sauna MS version of the software is required for all transient analysis
Simplify raw data control elements to obtain results quickly
New tools for simplifying raw data control elements
 For large models with complex power curves, simplification
tools are essential
 Simplify entire power curve
 obtain preliminary results
 identify critical zones of power curve, important for random data where
it's not obvious where maximum temperatures will be reached
 Simplify a range of control element
 many power curves have high power for just 5 or 10% of the total time
 simplify unimportant ranges while using fine resolution for areas
of high power
 Obtain results in minutes, not hours
Much larger models are possible
 100,000 nodes for Sauna Modeling System (previously 15,000 node limit)
 20,000 nodes for Sauna Standard (previously 7,500 nodes)
Product refinements
 Faster drawing of models
 Can interrupt drawing with "c" key (for cancel), useful when working
with large models
 Easier to change layer visibility
 When graphing timebased controls, can specify a time range or Yvalue
range (or both)
 Several bug fixes
Pricing: no change to pricing schedule

Sauna V4.50 Release notes.
