Default DEFINE_DPM_SCALAR_UPDATE problem in unsteady tracking

Hello everyone,

I'm running an simulation using the DPM, and I wrote an UDF that contains the DEFINE_DPM_SCALAR_UPDATE. The UDF is working well in steady tracking, but when I'm running unsteady tracking, FLUENT does not calculate the scalar that I've definid. It seems that every time step, fluent initializes over and over the UDF, and my scalar does not evolve throughout the simulation. Maybe I need to tell fluent to update de solution every time step. Does anyone had the same problem and have any solution?

You may have not defined a variable as general. Please send me your UDF to check.
