Grid Convergence Study: Initialize from Coarse Results
I'm performing a grid convergence study on a case involving a detonation channel (2D). The detonation wave takes quite a while to stabilize, and I was curious if there was a way in Ansys Fluent to initialize a finer meshed domain with the results from a coarser version of the same domain.
My previous attempts have produced warnings but no errors that prevent the case from running, but when reviewing the initial conditions in solution contours, the domain does not show the coarser detonation wave. Fluent version: 2022R2 Warnings Shown: Warning: read-data: data size does not match current grid Warning: case and data files are inconsistent; zone 2, case [1,727800], data [1, 182000] How I've tried previously: Calculation Activities -> Automatically Initialize and Modify Case -> Edit -> Initialization Method -> Use Solution Data From File -> <select data file> Does anyone have any experience with this? Is what I'm attempting even possible in Fluent? Thanks in advance for any advice/help you can offer. |
You need to use a interpolation file to transfer data from one mesh to another. In the same ribbon as read there is a interpolate action. With this you can select which region you want to export or import to as well as which quantity you want to export into the file.

Thank you very much for your help, alphaNOVA. The simulation seems to be running well, and I learned something new about Ansys Fluent. Have a great day!
