Steady versus Unsteady VLM #10

Closed bharswami closed 4 years ago

bharswami commented 4 years ago

Aaron Won't there be a significant difference in force values between steady and the settled values of unsteady VLM? Bharath

aarondettmann commented 4 years ago

Hello Bharath, I am not sure I understand your question correctly. Could you please try to rephrase your question. What do you mean with steady and settled values of the UVLM? And why would there be any difference in the force in your opinion?

Please note that PyTornado does not yet support UVLM analyses (though support for it would be desirable in the future).

In steady VLM there is no time variation for the forces. There is just one fixed value. In unsteady VLM, the forces vary with time. It will asymptotically settle to a value. My question is will this settled value be exactly same as the steady VLM case.

In comparing with my UVLM code and Matlab Tornado, I find that the forces aren't exact.

Could you please clarify this?

Closed. Duplicate question, see issue #14
