WebWhen creating the periodic boundaries, I disable “Automatic Compute Offset” and input the offset manually, as the offset is the same for all angles of attack. However, when I close the interface setup window and re-open it, “Automatic Compute Offset” is enabled again…. Problem 2: This is causing issues in the parametric study. Web26 de jul. de 2024 · There is new modelling in transport, turbulence, thermodynamics and combustion and useful new generic tools, e.g. more user-defined functions (Function1) for time-varying boundary conditions. There are improvements in performance and reliability of numerics, e.g. for multiphase and compressible flows, and general usability, e.g. bash … WebAn arbitrary number of minor and friction losses are considered to describe the system in terms of head losses. The boundary condition also provides the opportunity to specify the head in relation to a reference elevation. System changes during operations are modelled through Function1 variables, which enables time-varying inputs. des althorp
