heat source (W / m ^ 3) with distributed values ​​(voxels) in a domain

Hello!
Same questions:

- A heat source (W / m ^ 3) with distributed values ​​(voxels) in a domain should not be a absolute source, it should be a source, added to the temperature, there already exists. Is there any easy procedure?

- How can known voxel values ​​(sub-volumes) describe correctly a heat source? e.g. import the geometric voxel centre values and heat values as spreadsheet file and interpolation as nearest neighbor might not describe correctly the voxel distribution and the total energy!

Does anyone have an answer?

Thanks
Markus

The attached file shows a model with a turning disk. At first time steps T_ min decreases, that shows an absolute source. I need an energy source, in which the energy/temperature also increases in this source domain with sub-domain (voxel) division.
Also with this voxel thinking it is not save, that the total energy of 1 kW distributed over the energy domain is right.
There are any tips?
