Hello everyone, I am making a filtration model of a 2.5 km long earth dam in FLAC 3D 7.0 in order to generate the water table, the computational domain is complex and is made up of hexahedral, tetrahedral, pyramid, etc. elements. . The simulation takes a long time to advance even though I am using a high-end PC, any recommendations from experience?, to help the simulation advance faster. Reviewing the FLAC 3D Manual they indicate that for a filtration model the mesh must be regular and formed only by hexahedrons, this is not applicable in reality, since dams are complex structures where the foundation and body can only be represented by a mesh made up of different types of elements. Could someone with experience in earth dam seepage simulation in FLAC 3D give me some recommendations? Thank you very much
