Hi，
My external data contains 4 columns, which are radius,degree,height and power, namely: R(cm), fai(rad), z(m), power(W/cm3)
The external data are got in cylindrical coordinate by another program.
I have no idea how to import external data in cylindrical coordinate to comsol.
Maybe my former posed question was not say clearly, so I consult you again and thank you in advance.
