Dear all,
When I divide the grid into 400x9000x1 in DEM, the following error will occur. Is this the grid exceeded? Then I checked the code, but I didn’t know how to solve it. Could you help me solve it? thank you.
The limit is 5000 cells in each direction. If you really want more, you can edit the limits in param_mod.f. Look for
INTEGER, PARAMETER :: DIM_J = 5000
and increase the value of DIM_J. Make sure you build the solver so the change is taken into account.
Jeff,thanks.
I tried your approach, but it failed when I built the solver, what else do I need to change?

Somehow the buid fails when param_mod.f is copied into the project directory.
Maybe you can try to edit the original file in
/ncsfs02/xiaodong/anaconda/conda/envs/mfix-21.1.4/share/mfix/src/model
and build again (make a copy of it first).
Hi, Dr. Dietiker
I met the same problem when i modified the source code and compiled them without overwriting the original files. It warns “first defined here”. Do we have to overwrite the original file before compiling? Why can’t some source code files be compiled in the normal way, that is, remaining the original code files? Is there an alternative method? After all, it is not convenient to overwrite the original codes when running multiple simulations.
Thank you.
In general, you do not need to overwrite the original file, and you should copy the file into the project directory. There is an issue with param_mod.f and we are currently looking at it. I apologize for the inconvenience. Thank you for your patience.
