Dear All,
I am trying to undertand how the dynamicMeshDict file is written. I have understood that I have 4 parametres and I have to set some fields. Actually, I don't know the syntax that I have to use. Could anyone help? Is there a good documentation about this solver? Thanks a lot, Samuele. Here is my dictionary and below the error that I get. Thanks again, Samuele Code:

Hi Sam,
The motion solvers give very little indication as to how to format. The best way to find out (although slow) is to read the code for the constructor and see what it expects when reading certain keyword. Just guessing based on this error there probably needs to be a subdictionary or extra entry that defines the coefficients of the quadratic function for the diffusivity. |

The files are in $FOAM_SRC/fvMotionSolver/fvMotionSolvers/displacement/laplacian (for the displacementLaplacian motion solver which you appear to be using. In the *.C file, it shows that you should be looking for an object of type motionDiffusivity. I don't know where that is, so you'll have to look for that one (doxygen is your friend)
