    Remote Loads/Mass

      I have created a printed circuit board with split line profiles of some of the heavier components. I want to mass load the split line areas with the component weights so that I can get an fairly accurate resonant frequency. I tried the remote load option under the Load/Restraint icon but I am having problems when I try to run the frequency analysis. The error that comes is "Non-positive definite Moment of Interia matrix at Remote-Mass 4". Has anyone ever run into this and if so, what is the solution. Thanks for any help.
