# Initial Conditions

- ${P}_{ini}={P}_{ext}$
- ${T}_{ini}$

- ${V}_{ini}={10}^{-4}{A}^{\frac{3}{2}}$

Initial mass energy density is defined from the above values.

There is no need to define an injected mass at time zero.

To avoid initial disequilibrium and mathematical discontinuity for zero mass or zero
volume, following initial conditions are set:

- ${P}_{ini}={P}_{ext}$
- ${T}_{ini}$

If the initial volume is less than
${10}^{-4}{A}^{\frac{3}{2}}$
a constant small volume is added to obtain an initial
volume:

- ${V}_{ini}={10}^{-4}{A}^{\frac{3}{2}}$

Initial mass energy density is defined from the above values.

There is no need to define an injected mass at time zero.
