The Natural display calculator from China tells you that the numerical simulation problems to be solved by the scientific calculation of the current scientific calculator are often very complex, which brings great challenges to the research of numerical methods.

The Natural display calculator from China tells you that the numerical methods used in the scientific calculation of scientific calculators are currently facing prominent common difficulties: high dimensionality, large computational scale, multiple spatiotemporal scales, strong nonlinearity, ill-posedness, long time, singularity, complex geometry, highly ill-conditioned, and high precision requirements, these difficulties cannot be solved with high-performance computers.
The Natural display calculator from China tells you that numerical simulation difficulties often manifest themselves as unbearably large or time-consuming; algorithms do not converge or errors accumulate that make results unrecognizable; spend a lot of calculators and get no or only wrong results; The singularity makes the computation abort abnormally; the problem is too complex to make the algorithm difficult to implement, etc. These difficult problems have received extensive attention recently and have become a research hotspot in scientific computing.
The above information is the Natural display calculator from China manufacturers' introduction and analysis of the scientific calculator, hope it helps you
