Dear Jonkman
Hello, I had a problem during reading the Elastodyn code, so could you please help me to solve the problem? When I read the code of ElastoDyn I found a piece of code for calculation the Reduction shape functions and This code is necessary to calculate the linear velocity of elements of blade. I don’t quite understand the meaning of Reduction shape functions and why do calculate like this?
! Integrate to find the blade axial reduction shape functions:
DO I = 1,3 ! Loop through all blade DOFs
DO L = 1,3 ! Loop through all blade DOFs
AxRdBld ( I,L ) = 0.5*p%DRNodes(J)*( &
p%TwistedSF(K,1,I,J,1)*p%TwistedSF(K,1,L,J,1) &
+ p%TwistedSF(K,2,I,J,1)*p%TwistedSF(K,2,L,J,1) )
p%AxRedBld (K,I,L,J) = AxRdBld(I,L)
ENDDO ! L - All blade DOFs
ENDDO ! I - All blade DOFs
Thank you !
