Finding inertia of i beam in abaqus fea

Finding inertia of i beam in abaqus fea

Finding inertia of i beam in abaqus fea

(OP)
Hi,
Im relativly new to Abaqus and ive created an i beam by inputtin the properties, h,b,t1,t2,t3etc... The beam must create its moment of inertia from these properties. Ive checked the input file but that says the steps ive done rather then then what abaqus is producing.

Another problem ive been having is im trying to get the natural frequency of a beam. Im wondering how to apply a modal mass to the beam. ive tryed applying a load but the load does not effect the natural frequency. What I have done which works is increased the density to simulate the mass I want to apply and I get what im looking for but I can see this causing problems further down the line in analysis.

Any help would be greatly appreciated.
Thanks
