Hi, i have an error in powergui block

when i drop powergui block in the simulink window , i get some errors that does not run my block i get these errors "Warning: '' is not a valid model name because it is not a valid MATLAB function name. > In powergui Warning: '' is not a valid model name because it is not a valid MATLAB function name. > In powergui Warning: Could not evaluate MaskDisplay commands of block 'untitled/powergui': Undefined function or variable 'dispMessage'.

Change the name of your Simulink file. You already had a Simulink file named with "untitled.slx".

THANKYOU!

Warning: You have required continuous-time simulation of a system containing switches nonlinear elements.

The ode23tb variable-step stiff solver with relative tolerance set to le-4 generally gives best accuracy and simulation performance. For some highly nonlinear models it may be necessary to set the "Solver reset method"

parameter to "Robust".

See "Improving Simulation Performance" chapter in SimPowerSystems documentation additional information on how to select an appropriate integration method.

To ignore SimPowerSystems warnings, select "Disable SimPowerSystems warnings" in the Powergui Preferences tab. Any one can ans this?
