ramp or step input?
(OP)
In a static structural non-linear analysis, what difference is there between applying a load as a step or a ramp with 'kbc' ?
Does it affect results?

RE: ramp or step input?
If more substeps are to be done during one time step, then it ramped loads should lead to a better convergence.
But I don't think a raped load would lead to deferent results in the case of statical analysis. Provided the analysis converges.
But in the end, just try it a see what it happens!

RE: ramp or step input?
Thanks. Yes in fact I had convergence problems when my loads were stepped: I have a very large amount of loadsteps including a large amount of substeps.
Ramped loads give better convergence.
