Use the Systems panel to create rectangular, cylindrical and spherical coordinate systems. Use this function when you want to define nodes, loads and constraints in a different coordinate system.
Reference systems: Used to define the entities. For example, nodes created or assigned to a reference system are defined with respect to their reference system. Reference systems are sometimes referred to as the local input coordinate system of an entity.
Analysis systems: Used to define analysis quantities at a node. These are useful for defining constraints oriented in non-global directions.
The Systems panel contains the following subpanels and command buttons:

By System IDThis option assigns the ID of the coordinate system to the selected elements. How each analysis code interprets this information varies. For visualization purposes, the local x-axis of the selected system is projected onto the face of the shell elements. If you later modify the system, the element material directions change implicitly.
By System AxisThis function assigns a material angle to the selected elements or properties, which is defined as the angle between the node1-node2 direction and the projection of the selected local axis onto the surface of the shell element. How each analysis code interprets this information varies. For visualization purposes, the selected axis is projected onto the face of the shell elements. Any changes you subsequently make to the specified system has no effect on the elements. In Abaqus user profiles:
By VectorThis function assigns a material angle, which is defined as the angle between the node1-node2 direction and the projection of the selected vector, onto the surface of the shell element, to the selected elements. How each analysis code interprets this information varies. For visualization purposes, the selected vector is projected onto the face of the shell elements.
By AngleThis function assigns the specified material angle, which is defined as an angle from the node1-node2 along the surface of the shell element, to the selected elements. How each analysis code interprets this information varies. For visualization purposes, Altair HyperMesh rotates the node1-node2 edge of the element about the element normal through the defined angle.\
