I'm Silu Pei, new to OpenLCA and impressived by its powerfull functionalities.
Right now, I'm modeling a waste incineration plant which comprises of a incinerator, an air pollution control (APC) system and a wastewater treatment plant (WWTP) arranged in series. However, the effluent (waste flow) from APC does not connect to WWTP and I can't mannually connect by set provider nor drag. The catlog when I'm trying to set provider is presented as below.
Is there any solution to this problem? Your help would be much appreciated!
