4. Development of MHD Simulation
We shall present a short history of the development of the 2 and
3-dimensional global MHD simulations and evaluate their future.
We can recognize the pattern of a 4 fold increase every 3 years or
a 10 fold increase every 5 years when we look at the development of
the MHD simulations from the point of view of the number of grid points.
The computation time and the necessary computer memory increases in
linear proportion to the number of total grid points.
It is necessary to make the computation time of one time step advance
less than 10 seconds in order to carry out practical MHD simulations.
The required computer memory in VPP500 and VPP5000 is 2.5 times of
capacity to the key variables (160 Ng=2.5*64 Ng) in MLF for both
