A common issue with weight visualisation is the correct setting of the minimal global id. This occurs because may choose to start the global ids with "0" or "1", which makes the mapping between weights and grid data difficult. Another issue occurs, if the model did not define the respective global ids. In this case YAC will generate them, which makes mapping of the weights to data from a grid file impossible. [Nils](@k202160) proposed to only support the grid data written out by the YAC debug function. Both above mentioned issues do not apply in this case. [@Andrea](@k203161): as the main user of weight visualisation, what do you think about this simplification?
