Re: TCQUENCH

Hi Anna,
Thanks for the precise answer.
I have nevertheless some question about quenching
In the case i use USERDUMP with SUM=UDQUENCH,

1) how can i attach the birks parameter to the material ID?

2) Can i apply quenching to only 3 materials Id ?

3) How is the birks law implemented ? Do you adjust the Birks parameters for
charge> 2 ?
