Transiant analysis of pressure
 
Hi,

I want so solve a pressure problem.

I have a big volume of water. I'm assuming that the wall are rigid with no deformation. I have a pressure inlet and all other face are wall. I want to insert a pressure in the pressure inlet and I want to know how long it will take to pressurize all the volume. I also want to know what would be the difference of pressure in the transient regime.

The analysis is:

Type: Pressure-Based

Time : Transient

Material : water liquid (udf to define the density)

boundary condition : pressure inlet ( gauge total pressure :200psi) for the inlet, the other boundary are wall

Solution method simple

But when I run the simulation I have a divergence. Does someone have already did something similar.

Thanks
