Bed stress coefficient ERROR

Youngling Posts: 3 Join Date: 5/21/22 Recent Posts
Hi everyone. I have encountered an error about bed stress. The simulation stopped at part five. It says "ERROR Zero or negative value found for Bed stress coefficient" in the diagnosis file. How can I fix this? This happened after I created a space-varying roughness file. I have attached the diagnosis file, MDF and roughness file for your reference

Sincerely,
James Paul

UPDATE: I was able to solve the problem by checking the rgh file for zeros or negative values generated after exporting before copy and pasting the values inside the file

I am making a spatially varying roughness file and everytime I generate this in QUCIKIN it produces negative values even though I have specified the values I wanted. Have you had this issue?
