I am using Abaqus to model the penetration of water through a specimen. Unfortunately, I have a problem.
My job is successful. However, when I analyze the result, it seems that the diffusion "happens" only through the first mesh elements.
Indeed, if the number of element is equal to 1, the water diffuses through the all specimen. But if the number of elements is equal to 10, the water diffuses only through the first mesh elements. For information, my teacher told me to choose "Heat transfert" as Element type, and my step is a "Mass diffusion".
Could you please help me ?
Thank you a lot.
