| X7058 | FATAL ERROR: X7058 | One of the nodes in the Interpolation Constraint (RBE3) has no mass assigned to it. |
| Cause: | The interpolation constraint definition contains one or more nodes that have no mass associated with them. Both the independent nodes and the dependent nodes must have some mass assigned to them. | |
| Action: | Check the nodes assigned to the interpolation constraint and make sure that every node has some mass assigned. | |
| Remarks: | A common Nastran procedure is to define a grid point in space to be the reference node for an RBE3 constraint and to assign a point load or mass to the node to be distributed over the independent nodes. You must assign a concentrated point mass to the reference node to accomplish this in Autodesk Explicit. |
