我们提出了一个新版本的巴勒莫流体动力学模型的等离子体conned在科罗环，基于regridding算法，确保有限的变化，在网格点的物理变量。该代码提供了一个准确的描述色球-日冕过渡区的动力学，尽管非常陡峭的温度和密度梯度，即使在耀斑般的瞬态。新模型可以用来合成，连同X射线发射，光学薄发射起源于过渡区，主要是在EUV波段。在这里，我们展示了样本结果。
We present a new version of the Palermo- Harvard hydrodynamic model of plasma conned in coro- nal loops, based on a regridding algorithm which ensures limited variations of thermodynamical variables across grid points. The code provides an accurate description of the dynamics of the chromosphere-corona transition re- gion, in spite of the very steep temperature and density gradients, even during flare-like transients. The new model can be used to synthesize, together with X-ray emission, the optically thin emission originat- ing from the transition region, mainly in the EUV band. Here we show sample results.
