heal.abstract	Realistic selfconsistent calculations of unconventional superconductivity ina heavy-fermion material are reported. Our calculations for UPd$_2$Al$_3$ startfrom accurate energy band dispersions that are computed within the localspin-density functional theory and provide Fermi surfaces in agreement withexperiment. Using physically motivated, realistic pairing potentials it isshown that the superconducting gap has two lines of nodes around the z-axis,	en
