We obtain the phase diagram for the Blume-Capel model with bimodaldistribution for random crystal fields, in the space of three fields:temperature, crystal field and magnetic field. We find that three criticallines meet at a tricritical point, but only for weak disorder. As disorderstrength increases there is no tricritical point in the phase diagram. Weinstead find a bicritical end point, where only two of the critical lines meeton a first order surface in the H=0 plane. For intermediate strengths ofdisorder, the phase diagram has critical end points along with the bicriticalend point. One needs to look at the phase diagram in the space of three fieldsto identify various such multicritical points.
