I am using Radioss Block 51 format which supports M37 material card. But I am unable to use EIGRL card to do a modal analysis of a tank model, a structure in which the fluid solid elements are filled. Any help?

Alternately, If the fluid elements are modelled using MAT10 card in the Radioss Bulk format, I get error 14 message. How do i get the natural frequency of a structure in which the fluid elements are filled with? Any help please?

    HI Malar,

    I may not be able to comment on the the Radioss Block part of the query but the part concerned with the radioss bulk is certainly a portion on which i could suggest.

    The Error 14 indicates an invalid property error and there is every chance that the PFLUID FUNCT option is not highlighted in the property PSOLID card.
