Hi,

I am trynig to set up a moving mesh following a chemical reacting front.
I want to move the boundary in order to follow the reacting front and so ablate the domain.

I got familiarized with mesh deformation (point displacelement, boundary velocity, ...).

My problem is the calculation of the cell values after the mesh moved. For example : if there if 1500 kg/m3 of coal in a cell, when its volume has been halfed the new value is 3000 kg/m3. I would like this value to still be 1500 kg/m3 after the mesh moved.

Do I have to turn on or off something in a motion solver ? Any idea ?

Best regard,
Nathanael.
