Defining prescribed mesh velocity in Deformed Geometry physics

I am modeling the dissolution rate of a particular particle inside water using both the Transport of Dilute Species and Deformed Geometry physics.
There's only one dependent variable in "Transport of Dilute Species" physics (c). I do have a relation for the prescribed normal mesh velocity section in "Deformed Geometry" physics. But, this relation contains the partial derivative of "c" (from transport of dilute species) with respect to time ON the surface boundary of the particle! this is the tricky part I do not know how to approach.
I want to know how to use the variable "c" calculated in one physics and use it and its derivatives in other physics involved.
I'd appreciate it if you could help me with that.
Thank You,

The time derivative of c is available as ct and the first and second partial derivatives of c with respect to x are available as cx and cxx respectively.
