Hello, developers！When I was learning “conveyor belts” in an advanced tutorials，I’m prompted Fortran source files exist for this project, but there is no custom solver in the project directory. So I tried to build the solver, but there was a problem with the picture, how can I solve it?
In addition, I would like to ask if you can recommend some learning materials to me if I have no foundation in this area？
Looking forward to any possible answers! Thank you very much!
Please see The case run well in mfix-22.1,but has error in mfix-22.2.2 - #6 by cgw
If you can upgrade to the latest mfix, this problem should go away. If you are not able to upgrade mfix, then downgrade numpy as explained in the linked post.
