  Hi, I'm working in the Metric (um, kg, uN, s, V, mA) system. I'm using coupled pore pressure element CPT217. I am using an APDL command in Transient Structural to collect the fluid flow flux X (FFLX), fluid flow flux Y (FFLY) and fluid flow flux Z (FFLZ). In all documentation I found and in the output files I cannot find the exact units of this "Fluid flow flux". What is the unit of Fluid Flow Flux? Is it um^3/s? Was the flow flux normalized by the volume of the element?

  You need to assume the units in APDL. If you are using command snippets make sure that you use the same units in the snippet that you selected in workbench. For example if you are using Metric (um, kg, uN, s, V, mA) specify the porous media properties in the same units. You could use this - https://simutechgroup.com/detecting-units-with-an-apdl-commands-object-in-ansys-mechanical-workbench/-to avoid mismatch.
