Updating expressions based on previous time

      Hi, I was wondering if it is possible to update an expression for a new timestep, based on the expressions at the previous timestep.

      For example consider the expression named m: m(t+dt)=m(t)+...

       

      Regards,

      Maarten

      I think it's on the "to do" list. One of the problems is you'd then need to write in some other functions to stop the problem running away or oscillating between two solutions. It is possible in UDFs.
