    Normally for a fixed - free beam, we was constraining all freedoms (T and R) at fixed end

    I want to use spring at fixed end instead of constraining all freedoms in order to agree experimental modal results

    what I want that

    Hi,

     

    You can use CELAS or CBUSH element which will be fixed at one end and provide stiffness to the spring in the desired direction.
