model that simulated in 1.8.1 doesn't with 1.9beta3

[Bill Janssen]

The attached model Simple_Brake_Tests.Test1 worked with 1.8.1, but with 1.9beta3 I get the following error:

% ./Simple_Brake_Tests.Test1 -r test1.csv -override "outputFormat=csv"
stdout            | warning | Error solving nonlinear system residualFunc30 (size 1) at time 0.254

Postponed until 1.9.1

Works in r20781 (and probably also much sooner)
