I am performing dynamic simulations using the dynamic load model CMLDBLU1, composite load model. I can run the system (with all machine models) without problem when I do not include the load model. After I initialize the case with the load model all the voltages go to -1 p.u. Then when I run that system the output is all NaN. I am not sure why the voltages get set to -1, but I believe that is what is causes the NaN output.

The load model:

/ Bus, Model, ID, 'CMLDxxU1', 12, IT, 0, 132, 27, 146, 48, CON(J) to CON(J+131) /
