Greetings, esteemed researcher. I'm currently constructing the geometry of a plate heat exchanger (HX) in COMSOL Multiphysics. Upon creating an array of selected objects, I attempted to perform a "Form Union" operation for the final geometry. However, I encountered an error message: ''Boolean geometry operation failed'', as depicted in the attached screenshot. I would greatly appreciate any assistance in comprehending and resolving this matter. Thank you
