@desc
Reset the hydro variables when K is changed.
Unlike the routine above, this actually gives a solution to
the constraints.
Only two cases are given as the general case is transcendental.
We find this by holding rho * enthalpy fixed and assuming a
polytropic EOS.

Reset the hydro variables when K and Gamma are changed.
This is according to Shibata in astro-ph/0412243 (PRD71 024014) in
which he switches K and Gamma after initial data setup,
but keeps the internal energy constant.
Note: this works only with one refinement level
