"Initial conditions solve failed to converge" Error

Hello everyone,

I'm currently using Matlab 2014a and just started to use the simulink to simulate Op-Amp behaviour:

Unfortunately, I can't run the simulation due to "Initial conditions solve failed to converge" error. Here's the screenshot of Diagnostic Viewer:

What can I do to fix this error?

Please help, thanks.

Dear Asyraf,

My guess would be that your op-amp can not be modelled in this way due to a modelling error. I would suggest the following model:

Reference: OpAmp (Wiki)

Thank you Christiaan. Finally can get the Op-Amp model up & running without error.
