Multi-viewpoint observations of coronal mass ejections (CMEs) provide critical insights into their often complex morphology. This complexity can result from internal structural distortion, interactions with the ambient magnetic field, or projection effects. In this study, we examine a morphologically complex CME observed by SoloHI, integrating additional remote-sensing data and modeling the eruption using the thermodynamic MHD model CORHEL-CME. We perform and compare simulations assuming both single and dual magnetic flux rope (MFR) configurations. Our analysis indicates that the observed CME structure is best explained by the interaction of two distinct MFRs, rather than a single flux rope, highlighting the importance of combining multi-perspective observations with advanced modeling to accurately interpret CME evolution.
