How to change the default solid material in Fluent 2020

      I want to modify/change the solid material in Fluent for thermal analysis which is set to Aluminum by default. As the material has already been assigned to all existing boundaries, I can not delete it from the material tree; otherwise, I get the error that the material is already in use at the boundaries and the zones. A workaround is to define a new material and change the boundary material one by one from the boundary condition tree and then to delete the aluminum from the material tree. Doing it this way is very time-consuming when you have several boundaries. In my case, I have more than 30 walls and different zones, which is nearly impossible to do this way. Alternatively, another ugly way is to modify the values associated with the aluminum from the material tree to correspond to the material of interest, which may confuse others. Any suggestion on how to quickly and neatly add material and fluent take care of replacing it at all the zones and the boundaries instead of manually changing them?
