How can FLUENT be used to model a transient problem with changing geometry?
 
Hello all,
I am just new in using FLUENT and trying to acquint myself with the software, considering using it (FLUENT) to model a multiphase
flow (Fresh concrete paste). The fresh concrete is characterized as a Bingham fluid with its rheological parameters (yield stress and plastic viscosity) determined experimentally.
The geometry to be modeled is a truncated cone (both ends open). The end with larger diameter is placed on a solid base and filled with concrete from the top. When filled up, the top is leveled. Instantly, the cone is lifted and the concrete is allowed to flow radially over the metal base. At timed intervals, the diameter of the concrete is measured.
How possible is it for me to achieve that using FLUENT? That is, setting the problem up and plotting the snap shots of the flow at intervals. In addition, the distribution of velocity values need to be plotted.
Your help is a welcomed one.
