Why Three-Phase Transformer 'Specify initial fluxes' setting is not working?

In R2019a the following option is not working properly using the Three-Phase Transformer (Two Windings):

Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation

Specify initial fluxes:

If selected, the initial fluxes are defined by the Initial fluxes parameter on the Parameters tab. The Specify initial fluxes parameter is visible only if the Simulate saturation parameter is selected. Default is cleared."

The Initial Flux values are not shown in the parameters tab.

This is a bug in R2019a. To set the Initial flux in R2019a, follow the workaround below.

Please follow the workflow mentioned in the documentation.

After that, please use the following code, to set the initial flux parameter:

set_param(gcb,'InitialFluxes','[0.8  -0.6 0.4]')
