[asking]

Hi,

I am running a simulation of a vibrating cylinder subjected to a constant flow rate. The model works fine and the cylinder moves as expected.

I saved the simulation every 100 time-steps and I have problems when I resume it from the last saved time-step in a different computer. Basically, the scaled residuals increased drastically and most of the parameters that I am saving also increase significantly.

From time step 14000 to 14001
Lift: from -0.02 to 0.45
Yplus: from 0.86 to 2.29
Drag: from 0.07 to 9.88

Due to this increment, eventually my model fails due to negative cell volume problem.

I resume the simulation from Fluent going to File - import - case and data, and selecting the last saved time-step. Then, I copy the UDF with its corresponding folder "libgen" and just run the simulations.

Any suggestions would be really appreciated.

Regards
