Modes to find
I have been working on some tanks models with the "Modal" module. I have been collecting good results regarding the modes of the convective mass (within the order of 0.1 to 0.3 Hz), but I have not been doing very well when I need to collect the modal information associated with the impulsive mass. The number of modes that I ask the program for is a bit exaggerated (more than 5000 modes and still don't get the impulsive modes), so I would like to know if there is any possibility to limit this number of modes, i.e. that the program only calculates the modes in one direction only, since a cylindrical tank fortunately has symmetry.
Thanks a lot!!
