In [[mathematics]], the '''Courant–Friedrichs–Lewy condition''' (CFL condition) is a condition for convergence while solving certain [[partial differential equation]]s (usually [[Hyperbolic partial differential equation|hyperbolic PDE]]s) numerically. It arises when [[explicit method|explicit]] time-marching schemes are used for the numerical solution. As a consequence, the timestep must be less than a certain time in many [[explicit method|explicit]] time-marching [[computer simulation]]s, otherwise the simulation will produce wildly incorrect results. The condition is named after [[Richard Courant]], [[Kurt Friedrichs]], and [[Hans Lewy]] who described it in their 1928 paper<ref>R. Courant, K. Friedrichs and H.

'''Indosiar''' is a privately owned national [[television station]] in [[Indonesia]], which has been operating from [[West Jakarta]] since 1994. It was founded and is owned by the Salim group.
For example, if a wave is crossing a discrete grid, then the timestep must be less than the time for the wave to travel adjacent grid points. As a corollary, when the grid point separation is reduced, the upper limit for the time step also decreases. In essence, the numerical domain of dependence must include the analytical domain of dependence in order to assure that the scheme can access the information required to form the solution.


The station has a strong focus on cultural programming, such as a program dedicated to [[wayang]] performance. At the same time, it is also becoming prominent in programs such as reality, talk shows and drama series, particularly "sinetron" [[soap opera|soapies]] with themes such as love and family.
The CFL condition is commonly prescribed for those terms in PDEs which represent [[advection]] (hyperbolic part of the PDE). For one-dimensional case, the CFL condition is given by

Indosiar is a privately owned national television station in Indonesia, which has been operating from West Jakarta since 1994. It was founded and is owned by the Salim group.

The station has a strong focus on cultural programming, such as a program dedicated to wayang performance. At the same time, it is also becoming prominent in programs such as reality, talk shows and drama series, particularly "sinetron" soapies with themes such as love and family.

Its logo resembles the logo of TVB in Hong Kong, and there seems to be some association as Indosiar broadcasts some Hong Kong programs such as The Return of the Condor Heroes.

Indosiar shows some Korean, Japan, and Taiwan dramas, for example: Korea: Hwang Ji Ni (or Hwag Jin Yi), Jewel in the Palace (Dae Jang Geum), Princess Hours (Goong), Prince Hours (Goong S), Full House, and 18 vs 29. Japan: One Litre of Tears (or One litre no Namida) Taiwan: Romance in the White House

Other popular Indosiar programs include singing competitions such as Supersoulmate Show, Mamamia, Stardut. Supersoulmate Show is hosted by Eko Patrio and Ruben Onsu, Mamamia is hosted by Denny Cagur, and Ruben Onsu, while Stardut is hosted by Choky Sitohang

Logos
