Hello Can you please paste the auxkernels block and the materials block? These just look like two different properties. Guillaume |

Hi @GiudGiud Here is the auxvariables, auxkernels and material blocks respectively: [./stress_excess] [./stress_excess_ker] [failure] |

can you try order = CONSTANT for the variable? I m not sure exodus output represents second order monomials right. I ll try to find a list of the ones we can represent in exodus |

Thanks @GiudGiud I changed the order=CONSTANT for the variable, but i got bad termination at the end of first time step: Solve Converged! ===================================================================================

Looks like a bug. Can you follow the debugging instructions and get us a backtrace? |

Hi all,
I wrote a simple material property, I need to have it either as material property or auxvariable in the model. To extract the value from material object to aux system (and save the parameter as another variable) i have used " MaterialRealAux", on the other hand i outputed the paterial property by seetting up "outputs = exodus" in the block. The code works properly, as expected.
So, the output of the parameter as material property sounds good, however the output of aux system does not match with it.
The results are completely different, figure below:
the figure shows the profile at first time step, red line outputed as material property and blue line outputed as auxvariable. here is the last time step:
The output of aux system is wrong at first step and does not chnage over time as should be.
why does it happen, i.e. auxvaribale shows wierd profile (like random values) while it just reads the data from material property.
