This table list the available output result sets that you can request from the thermal solver in Thermal/Flow, Electronic Systems Cooling, Space Systems Thermal, or Multiphysics.

Output request type	Result set in Post Processing Navigator	Description

Local Temperature Error Estimate	Temperature Error Estimates — Elemental****Temperature Error Estimates — Nodal	Temperature error estimate results estimate the local spatial discretization errors caused by the mesh used for the simulation of conduction. The elemental temperature error estimate, εT, is the maximum temperature difference of all boundary elements computed as follows:εT = max	TBE – fBE(T1, T2, ..., TN)	where:TBE are the calculated boundary element temperaturesTi are the N smoothed nodal temperaturesN is the number of nodesThe fBE function uses element shape functions to interpolate the nodal temperatures to the boundary elementThe error estimate is measured in units of temperature difference.These result sets are always computed for all elements and nodes.	εT = max	TBE – fBE(T1, T2, ..., TN)
εT = max	TBE – fBE(T1, T2, ..., TN)					where:TBE are the calculated boundary element temperaturesTi are the N smoothed nodal temperaturesN is the number of nodesThe fBE function uses element shape functions to interpolate the nodal temperatures to the boundary element

These result sets report the heat transfer coefficient values that are corrected via the Area Correction Factor or Area Override property of each element or node.

Displacements	Displacements — Nodal	Vector data equal to the displacement at node points. The software writes this result set only for coupled solutions.

Note:

• The software generates elemental result sets when the corresponding Results Location is set to Elements or Elements and Nodes. Elemental results are computed at element’s center of gravity.

• The software generates nodal result sets when the corresponding Results Location is set to Nodes or Elements and Nodes. Nodal results are interpolated from elemental results of the surrounding calculation points.

• The solid laminate physical property is only available in Multiphysics.

• The multi-layer shells are not available in Multiphysics.

• The convective boundary conditions are the following load types:Thermal Convective ZoneThermal StreamThermal Void
