Hi,

after a week of meditation at OpenFOAM sources and examples of dynamic layering, I made it works!

It uses interDyMPimple solver with movingConeTopoFvMesh and layerAdditionRemoval modifiers.

Here I described all steps: https://ilyasivkov.wordpress.com/201...h-in-openfoam/

Ilya.

Hi Ilya

This looks super promising. Thank you so much! Will give feedback before the end of the week.

Hi Ilya

This demo is really awesome, thank you again. I tried to recreate your results by editing the damBreakWithObstacle tutorial case and adding the specified files of yours and I think I got it. I want to simulate the regression burn in a solid rocket motor.

1. Do you know if it is possible to set the velocity (motionVelAmplitude) of the moving boundary according to a dynamic variable calculated at each time step in the solver?

2. Is it possible to set this velocity for each cell on the boundary?

I want to calculate the burn rate (mm/s) of each cell on the boundary and set the motionVelAmplitude equal to this.

Thank you in advance

Hi, PickIER,

As for motionVelAmplitude, it is always fixed. Field-dependent mesh movement is another powerful future op OpenFOAM, but I have not learned it yet.

As for the engine, I am not sure you need moving mesh. Maybe, two-phase solvers can be used.

Also I googled with "openfoam solid fuel mass flow" and found some articles:
