how do i solve the singularity problem in simulink?

Asked by Yunzhe Luo on 13 Aug 2018
I made this simple PV array and when i try to run i get the message shown below:
Derivative of state '1' in block 'testing/PV Array/Diode Rsh/BAL/Transfer Fcn' at time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
I tried to change the model configuration to discrete and continuous but seems not working. Can someone give me a hint about what to do with it?
