Hello,
I am trying to write the surface gradient (i.e. tangential derivative) of test function in cylindrical co-ordinates.
I wrote : (test(uTr)+test(vTphi)+test(wTz)) and got the error: "undefined variable vTphi.
I know that the formulation is (test(uTr)+test(vTy)+test(wTz)) in cartesian co-ordinates. I am trying to write the analogue of the expression in cylindrical co-ordinates.
Could someone help me with this?
