Hello everyone,
I am writing this because I am trying to model a dual circulating bed system using the TFM approach and I am having significant problems in attempting to run the simulation. I have tried to upload the geometry of the beds as an external stl file that I produced using Freecad (see the file named riser only) and as geometry using the available Mfix procedural curves (see file riser_mfix_geom) but the simulation keeps failing in both cases and I don’t know how to fix it (as of now, the error it gives is DT<DT_MIN, I have tried changing DT_MIN, or refining the mesh, but it does not appear to work). Furthermore, the file with MFIX preavailable geometries as since stopped working completely: it starts the run, but it is immediately stopped without even producing the mesh, but it does not give any errors. My final plan was to simulate the whole dual bed system using the stl file I made, but so far I have been unsuccessful, even in modeling only part of the apparatus. I need at least the riser results to compare them to experimental data. Please, can anybody help me to understand what is wrong with my simulation attempts? I am completely new to this kind of work and I don’t know what I can do.
