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 !
