Announcing Release of BModes and PreComp Codes


I am happy to announce that BModes and PreComp are now available on our website - thanks to our expert, Marshall Buhl.

Use BModes to generate flap-lag-torsion coupled modes for a rotating blade or a tower.

Use PreComp to obtain structural properties for composite blades.

By the way, I’ll be away on vacation (in India) until Dec 20th. Until then, please contact Marshall ( for help on downloading or installing the programs only. When I come back, I�ll be glad to entertain any usage-related questions.
