-The heat source is defined using the [HeatSource](https://docs.flexcompute.com/projects/tidy3d/en/latest/api/_autosummary/tidy3d.HeatSource.html){: .color-primary-hover} object. Users can specify the volumetric heating rate, which can be uniform or spatially varying using a [SpatialDataArray](https://docs.flexcompute.com/projects/tidy3d/en/latest/api/_autosummary/tidy3d.SpatialDataArray.html){: .color-primary-hover} object. The source can be applied to any structure within the simulation domain.

 In practice, one often wants to model a heater with external current applied. To model this Joule heat source, we can calculate the volumetric Joule heat generation using
 
-$$\frac{dP}{dV} = \frac{1}{\sigma}\left(\frac{I}{w_{heater}h_{heater}}\right)^2$$
+$\frac{dP}{dV} = \frac{1}{\sigma}\left(\frac{I}{w_{heater}h_{heater}}\right)^2$
 
 where $\sigma$ is the electrical conductivity of the heater material, $I$ is the applied current, and $w_{heater}$ and $h_{heater}$ are the width and thickness of the heater, respectively.
