Luminous red novae (LRNe) are relatively new transients that have the luminosity between classic novae and supernovae, initially classified as "gap transients". Even though many more "gap transients" have been observed by telescopes such as ZTF and Keck, their origin and physical processes remain mysterious. To initiate the study of the nature of LRNe, I built a 1D and 2D radiation hydrodynamic model with Guangqi, with the aim of reproducing their light curves. The models can take radiation energy, recombination energy, and shock heating into consideration, making them the most comprehensive models currently available. In this report, I will take the light-curve of AT 2019zhd as an example, and fit it with our 1D model. I will also present the versatility of 2D models in fitting the light curves.
