Friction Coefficient definition for each timestep

Dominique_Cracovia

Is it possible to add a functionality to an already existing object?

Let's say I've got 100 non-linear contacts and 100 analysis steps. I'd like to script a block or ACT app in order to be able to change a friction coefficient for each contact and each timestep.

I know there is a "Contact Step Control" object which allows to change Normal Stiffness.

Could you help me find a code example in the Ansys help in order to add this "friction control"?

Thanks!

This tells how to do it at the solver APDL level. You can create any user input interface you want, but in the end you need to get the values for TIME and FRIC into this ADPL format and pass this string to the solver input file.
