What should I do if my new boundary need to use the velocity of last moment in the code ? Should I define a new scalarField (vectorField) to store the value?

Dear Philip,
I am trying to apply a boundary condition of potential which is a function of time. It requires me to use temperature from temperature field(which is a function of x,y,z and t).The boundary condition of potential has three terms
a=373k-Ttip.It is sum of a , derivative of a w.r.t and integration of a with time. Can I get some help with this.
Thanks

Hi Siddhartha,

Please give more details, including, what value (or gradient or combination) you are trying to enforce on the boundary. In addition, please give details of what you have tried so far and why it has not worked.
