Problem related to usr_drag.f

Hi all,

I have attempted to utilize MFiX version 22.4 to run the user-defined drag model. Once I construct the solver, it indicates “Built Succeeded.” However, when attempting to start MFiX after the compilation step, the following problems appear.

Error from usr_drag.f:68

Error 9999: The user-defined drag routine was invoked but this

generic error message exits. Either choose a different drag law

or correct mfix/model/usr_drag.f

Kindly help me in this regard


Did you select the custom solver (the one you built)? It looks like the solver is not using your modified file. The error message you see comes from the original file.

Thanks for the response. I got it resolved!
