The main features of RheoChart are listed below. The best way to explore these features and to discover others is obviously to download the free trial.
Please note that not all the features listed below are implemented in the current version. These missing features will be added progressively. Please also note that the list is still not completed and/or finalised.
Not finding a feature? Would you like to see one of your preferred model implemented in RheoChart? Or you find that a material function would help you to better calibrate the parameters of your model? Don't hesitate to so that we can discuss what is feasible.

 Other outputs
 For all the material functions listed above, it is also possible to visualise all the stress components for that flow. For the multiramp shear stress rate function, the shear strain can also be visualised.
 Note: some properties (such as the shear stress decay function, shear stress relaxation function, shear rate in a creep experiment,...) are obtained using the more versatile "MultiRamp" properties.
Automatic Fitting  Parameters Calibration
RheoChart has the unique capability to fit model predictions against experimental data. This procedure sometimes referred as parameters calibration can be very tedious to accomplish manually. RheoChart can greatly simplify this procedure.
All parameters of a model (Generalised Newtonian models or Multimode differential viscoelastic models) can be estimated using several optimisation algorithm. These parameters can be bound by upper and/or lowerlimits or left to vary freely. Alternatively, parameters can be fixed.
Every material functions available in RheoChart can be used to curve fit experimental data. A fitting procedure can use one or more experimental curves simultaneously. A weight can be associated with each experimental curve.
