I've been trying to put my head data in my model using MODFLOW6 but I get the following error:
MFDataException: An error occurred in data element "strt" model "model" package "ic". The error occurred while setting data in the "__init__" method.
Additional Information:
(1) Unable to set data "strt" layer 0. Data is not in a valid format.
(2) Error occurred while adding dataset "strt" to block "griddata"
I already tried anything possible, the strt is an array from a raster (boundary of head table data), the raster is in .tiff format as well as the other layers of the model. Also, I've made sure that they have same pixel size and extent. How can I solve this error? Thank you
