I get the error below from my simulation

I have read the debugging procedure on the moose website and even created a debug executable yet I am still confused how to approach this problem.

Below is the error:

Hello

This is not a bug you dont need to use a debug version.
it s a physics model issue. see this failure in the log

ComputeMultipleCrystalPlasticityStress_abs: Constitutive failure
To recover, the solution will fail and then be re-attempted with a reduced time step.

building a debug executable is a good first step
next you want to use a debugger on that executable

https://mooseframework.inl.gov/application_development/debugging.html

and find when / where the constitutive relations are failing

I do also see this Nonlinear solve did not converge due to DIVERGED_FNORM_NAN. which according to the moose website:
99% of the time, this arises because a variable is not initialized and the material properties are evaluated out of bounds. Initializing all the variables in the simulation will fix the problem.

As you can see from my input script above, I am restarting from a previous simulation, and most of my variables are loaded from that simulation. Is there a way to initialize variables from a restart simulation?

All your auxvariables are not initialized. Are they just fir output?

99% of the time, this arises because a variable is not initialized and the material properties are evaluated out of bounds. Initializing all the variables in the simulation will fix the problem.

It's not always the case though. I think the message you are getting is clear where you are getting a failure. If it s from an uninitialized value, you will see it while debugging that message

When you say debug do you mean running my script with the debug executable?

no I mean follow these instructions
