UniformExcitation warning

Post by sjbrandenberg » Thu Aug 19, 2004 4:12 pm

When I use a UniformExcitation pattern, I get the following warning:

WARINNG: GroundMotion::getVel(double time) - we are having to integrate to get the ground velocities, are you happy with the integration scheme?

I realize that specifying acceleration, velocity and displacement is a more specific method of defining a ground motion that just using acceleration since no integration is required. Can I specify all three using a UniformExcitation pattern? If not, should I be concerned about the warning I'm getting? Should I abandon using UniformExcitation and switch to MultipleSupport instead?

you should worry about this kind of message if you use multi-support exciattaions.
