Dear all,

In my problem, the physical domain includes 1 big cylinder (denoted as C_0, filled with gas at low pressure(101 Kpa)) and 10 small tanks (denoted as tank_i, i = 0, 1, ..., 9, filled with gas at 1 Mpa).



The simulation process is to release the high pressure gas of each tank at a given time T_i.

At T_0, the computational domain is: C_0 + tank_0,

At T_i, the domain is : C_0 + tank_0 + tank_1 + ... + tank_i;

That is to say, the computationl mesh will change at time T_i.

My question is, which topoChangeFvMesh should I use? My I have your suggestion on implementing such simulation? Or are there any similar examples in the tutorial directory of openfoam?

Thank you very much!

Best,

Hong
