OpenFOAM Version : 2012
OS : Ubuntu 20.04 GCC : gcc v6.3 There are total 4 domains in the test case Domain 1. Long rectangular volume with mesh motion (10x10x1000 mm) Domain 2. 1st Cube interfacing with Domain 1 & 3 (10x10x10 mm) Domain 3. 2nd Cube interfacing Domain 2 and 4 (10x10x10 mm) Domain 4. 3rd Cube interfacing with Domain 3 and with outlet BC cyclicACMI interfaces are used between Domain 1-2, 2-3 and 3-4. Scale factors are used for cyclicACMI interface between 3-4. Even for small change in scalefactor from 1 leads to divergence. It has been tested with ideal gas, tabulatedEOS, SSTkW, KE models, small timesteps etc. (TabulatedEOS from https://github.com/Yuusha0/tabulated...icalProperties) Pressure goes outside of the bounds. If dynamicmeshDict is removed from constant folder case runs well. I suspect there is some bug in scale factor module introduced in the v2012 or it is not compatible with mesh motion. I wanted to ask if this observation is expected as I dont know complete limitations of this new capability and if no is there any quick fix to this issue ? Thanks |
