# evaluateHeatFlux

Evaluate heat flux of a thermal solution at nodal or arbitrary spatial locations

## Syntax

## Description

`[`

returns the heat flux for a thermal problem at the 2-D points specified in
`qx`

,`qy`

]
= evaluateHeatFlux(`thermalresults`

,`xq`

,`yq`

)`xq`

and `yq`

. This syntax is valid for
both the steady-state and transient thermal models.

`[___] = evaluateHeatFlux(`

returns the heat flux for a thermal problem at the 2-D or 3-D points specified
in `thermalresults`

,`querypoints`

)`querypoints`

. This syntax is valid for both the
steady-state and transient thermal models.

`[___] = evaluateHeatFlux(___,`

returns the heat flux for a thermal problem at the times specified in
`iT`

)`iT`

. You can specify `iT`

after the
input arguments in any of the previous syntaxes.

The first dimension of `qx`

, `qy`

, and,
in the 3-D case, `qz`

corresponds to query points. The second
dimension corresponds to time steps `iT`

.

`[`

returns the heat flux for a 2-D problem at the nodal points of the triangular
mesh. The first dimension of `qx`

,`qy`

]
= evaluateHeatFlux(`thermalresults`

)`qx`

and `qy`

represents the node indices. The second dimension represents time steps.

`[`

returns the heat flux for a 3-D thermal problem at the nodal points of the
tetrahedral mesh. The first dimension of `qx`

,`qy`

,`qz`

]
= evaluateHeatFlux(`thermalresults`

)`qx`

,
`qy`

, and `qz`

represents the node
indices. The second dimension represents time steps.
