### IC, $Q$, ${p}_{u}$, ${p}_{d}$

Defines the fluid initial conditions. If you want to set the initial conditions by this command, then parameter $\mathrm{ic}$ of the command PAR, FLUID2 has to be set to IC_COMMAND.

Parameter Typical value Description
$Q$ $0.0001968{\mathrm{m}}^{3}·{\mathrm{s}}^{-1}$ initial flow-rate
${p}_{u}$ $3878.4\mathrm{Pa}$ initial pressure at the beginning of the flexible tube
${p}_{d}$ $3876.4\mathrm{Pa}$ initial pressure at the end of the flexible tube
