RE: defference between principal coordinate system and shape coordinate sy

Morning Saranam,

Can you explain the FE problem & your the FE tool (software) you are using.  It sounds like a you are working a modal/dynamic problem & without knowing the above your principle coordinate system may be the global XYZ axis & the shape coordinate system is the element coordinate system.

Good luck,
jxc
