Using Block Lanzcos or Subspace for result is better
(OP)
I am meetting impediment in select Subspace method and Block Lanczos methodIn task simmers number riêng. Block Lanczos, first mode equal zero. Subspace mehtod, first mode don’t equal zero. Result of two different methods is different. Neither know I am have to who blunder where Neither, waitted you helps. And with respect to a large structures, Block Lanzcos method or Subspace methods for results is better. Thanks !

a) Read the documentation on both methods.
b) Fix your apparent problem with rigid body motion.
As for method, I always use the block lanczos unless the model is prohibitively large.
