I am looking for a toolbox that allows
i) Modelling of a shaft with ability to change properties along a direction.
ii) Modify end supports (ex: pin type, fixed, roller type, etc.)
iii) Conduct modal analysis, frequency responce, etc.
iv) Use of FEM to solve eigen value problems.
I am using PDE toolbox to try and achieve this but am unable to define the end supports to be pin type. (any advice on how to accomplish this would also be appreciated)
