Time, time step and nonlinear iteration information in material UDF

Hi there.

I am working on implementing a grain growth and recrystallization model into the user-defined material model. Since the model is history based, I need the time and timestep information inside of the material model. Right now I am working with fixed time steps and not using nonlinear iterations.

There is a UDF_MaterialModels manual which I got from Altair from the year 2012 were all the input variables (res()) are stated. I was discussing last year with Altair to add the time and timestep information into this existing array which has empty indices from 17 to 35 according the manual. I just tried to find if anything has been added and at least for 17 and 18 found some values.

Is time and time step and possibly number of nonlinear iterations already available in the res() array? Is there an update of the manual stating the additional values?

There is also another manual for user defined results which is also very old (from 2012). Is there also an update for it?

Thanks and best regards.
