Constant computation mode
When constant computation mode is set, the inter-bar and inter pole end-ring resistance and inductance values must be set by the user. The values are given for a reference temperature. In this case the inter bar end ring resistances and inductances are always a function of temperature (function depending on the material of the end-ring). Once again, the inter bar impedance can only take an average value, even if bars are not evenly distributed.
