Detailed Description
Problem generator for blast wave in cylindrical coords.
PURPOSE: Problem generator for blast wave in cylindrical coords. Can only be run in 2D or 3D. Input parameters are:
- problem/radius = radius of field initial overpressured region
- problem/pamb = ambient pressure
- problem/prat = ratio of interior to ambient pressure
- problem/b0 = initial azimuthal magnetic field (units sqrt(Pamb))
- problem/rho0 = background density
- problem/omega0 = initial azimuthal flow angular velocity
