Why do I receive an error when using Hysteresis Design Tool in SimPowerSystems 4.0 (R14SP1)?

I have a model that uses the Saturable Transformer block in SimPowerSystems 4.0 (R14SP1). I then select "Simulate Hysteresis" for the block and enter a file name for the Hysteresis Data MAT file. I include a Power GUI block, select Hysteresis Design Tool and Select "SI" for the "Parameter Units" pull down menu. I then save this model to a MAT-file with the same file name as the one specified in the Saturable Transformer block. When I simulate the model I receive the following error:

 One or more output arguments not assigned during call to 

 'C:\MATLAB701\toolbox\physmod\powersys\powersys\private\inithysteresis.p

 (inithysteresis)'.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

We have verified that there is a bug in SimPowerSystems 4.0 (R14SP1) in the way that the Saturable Transformer block handles simulating hysteresis with SI Units.

To work around this issue, use pu units in the Hysteresis Design Tool.
