I defined tendon number and tendon geometry.
And then I executed "recalculate". But some tendon type has been changed with "internal" letter and then I could not delete it. When I try it, the error message is shown with "Impossible to delete!".
What is this error message? What is the solution to be sorted out?
Tendon are impossible to be deleted, like any other elements, if they are used (activated) in the schedule. So, initially you just need to change this used reference and then you would be able to delete it.
