I am currently struggling with two issues in ModelBuilder both dealing with iterators. First I have situation where I have two model (Model1 and Model2). Both of these models produce a series of raster outputs (Model1_A, Model1_B, Model1_C...) and (Model2_A, Model2_B, Model2_C...). I need to sum the outputs from each model together so that Model1_A get added to Model2_A, Model1_B to Model2_B ect. as paired inputs. Is there a way to do this using iterators in ArcGIS Pro (Esri removed the run variable as list option from ArcGIS Pro). Additionally how would I create a workflow where every possible combination of outputs from Model1 and Model2 are summed?
