Moving surface velocity boundary condition

I want to give the moving surface velocity boundary condition as per attached equation.
Can anyone help how i can implement in OpenFOAM.

I am solving problem of solidification in Thin funnel shaped caster.

Hi prajodiya,

I think you cand do that with a codedfixedvalue BC, with that type of BC you can code the function, there are some examples of how use codedfixedvalue in youtube like this one

or the one from Tobias Holzmann

An alternative would be with groovyBC, but wou will need to install swak4Foam
