Simulation With cyclicACMI Scale factors crash with mesh motion
 

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

Any thoughts ?

Thanks
