Hello, everyone!
I'm working on the FEM simulation of electro-plasticity effect , with the coupled thermal-electrical-structural module of Abaqus.
And I need to write a constitutive model, with respect to electrical variables(eg. the current density), into an umat subroutine. but I don't know how to introduce the electrical variables into umat. -- As the temperature field can be passed into umat directly but electrical field cannot.
Any suggestions will be highly welcomed and appreaciated!
Wish you a nice day and thank u in advance!
