By default, all components of forces and moments are given with respect to the global system. If a local coordinate system is defined for the output request, all components are given with respect to the local system. The output quantity is computed by integration over a surface that is specified either directly in the output request or by associating an integrated output section definition (see “Integrated output section definition,” Section 2.5.1) with the integrated output request. Different output variables are available depending on the type of analysis. For coupled analyses the appropriate combination of variables can be requested. For example, in a coupled thermal-electrical analysis both SOH and SOE are valid output requests. Section output variables are not available for linear dynamic procedures.
