Measures as input to user written functions

Hello,

Is it possible to use a measure as input to the user input values of a subroutine? I want to use the previous values of a contact force in order to change the force's value in the current step i.e., I want to create a measure of a contact force and use it as input to its user written subroutine (cnfsub).

Thanks,

Josef K.

A measure is a solver variable. Only difference is that there is no error control on measures.

But compared to requests, they should be calculated at every integration step whereas the requests are only calculated at output steps. At least this was the case when I last used a measure and draw the conclusion that they are more or less useless. And I never looked at them since.
