![]() ![]() ![]() but, if ANSYS doesn't have resources on this, that may be my best option. 0 Computational Fluid Dynamics software Ansys Fluent 2020. I've been apprehensive about doing this because my C++ is rather limited, and I would need to learn the entire OpenFOAM solver architecture. ANSYS FLUENT will perform various checks on the mesh and report the progress in the console. Maybe the best approach to get details about the numerics is to study the solidBodyMotionFvMesh routine in OpenFOAM. Southpointe 275 Technology Drive Canonsburg, PA 15317 (T) 72 (F) 72 Release 14.0 November 2011ANSYS, Inc. ![]() Our new system does not have any sliding interfaces (the whole domain moves along a 2D sinusoidal excitation with rigid body translation) so that simplifies things. User Defined Functions Manual for use with Ansys Fluent 14.0 Computational Fluid Dynamics (CFD) software TRANSCRIPT ANSYS FLUENT UDF Manual ANSYS, Inc. vibrating) mesh? Does this put you in a non-inertial reference frame, and if so, under what circumstances can these non-inertial effects influence your solution, or maybe introduce more terms to the RANS equations that must be accounted for?nArrayAh okay, I like the relative velocity idea! Then maybe I don't need to worry about mesh position updates, except with respect to sliding interfaces. ArrayPerhaps a more ANSYS-specific question would be: since there are no citations, how/where was the relative velocity formulation in section 3.2.1 derived? And has this been validated against test cases? For example, I can see this working for a constant-velocity mesh, but what about a constantly-accelerating (i.e.
