Multiphase and DPM

I have a particle mass loading of 10%.

How could I use this value in ANSYS Fluent?

In Fluent, the volume fraction (particles volume / flow volume) is result of your DPM setup. After setting your DPM injection, particle size, mass flow rate, etc... and running 1 FTT (at least). You can count the particles within your system and evaluate yourself the volume fraction. In other words, you dont specify this value a priori.

Also, for DPM to work properly, the cell size should be larger than the particle size.

I performed a 2D simulation of the shock wave in shock tube using shock capturing method. Now I want to plot a graph of x-t (x co ordinate vs. time) for the shock wave in the shock tube. It was a unsteady with turbulent model, simulation using the Ansys Fluent. So, is there any way that I can plot x-t graph for the shock wave using the Ansys Post-Processing??

Thank You.
