There is no work around other than to make certain that joint coordinates are specified for all IPCABLE elements in the model.

This error can be verified by comparing the element stress results at the starting or ending element node produced by these commands to the stress at the starting or ending node computed by the following relationship: Equation "1" omitted where, F sub x = global X nodal force at starting or ending node, F sub y = global Y nodal force at starting or ending node, F sub z = global Z nodal force at starting or ending node, AX = element cross section area. The magnitude of the percent stress error at the starting or ending node of the element can be estimated from the following relationship: Equation "2" omitted. where, Symbol omitted sub err = percent stress error estimate, f sub x = total global X IPCABLE element load, f sub y = total global Y IPCABLE element load, f sub z = total global Z IPCABLE element load, Symbol omitted = element starting or ending nodal stress from Eq. 1. Rev. 2.2 As a work-around, the stress at the starting or ending node of an IPCABLE element can be computed from Eq. 1.
