# Use of piecewise constant variables I'm trying using a piecewise constant fonction in my vensim model, by defining an auxiliary with a look UP as graph. But i don't know how to define the equation subscripts correspondant to piecewise constant functions. If i put a constant, it will only considered the constant for all the dynamics. What is the right way to do it. Can someone help me? ##### Post Metadata - Net upvotes: 1
