Keep some cells of the starting model fixed within the mesh

Dear SimPEG users,

Hope you are all having a good start of the year. Is there a way to make cells of known information in the starting model fixed during the inversion process?

Regards

Easiest way I can think of would be to apply tight bounds on those cells.

The “upper” and “lower” properties of optimization.ProjectedGradient can be vectors of len(model)

I see. Thanks so much!

So to keep something at 3, set both to 3?

Yes, you can narrow the bounds to a single value by setting the upper and lower values to be the same.
