I tried to run the codes.
in PFC everything was ok but once I executed cfd_dropTest1.py, I saw "Python error: NameError("name 'ca' is not defined",)"
what is the reason. ca was defined already by "from itasca import cfdarray as ca"

There is no problem before running 'python setup.py install --user' as follows:
~/src/PFC3D_OpenFOAM/pyDemFoam$ python setup.py install --user
building version 2016.06.09
running install
running build
running build_py
running build_ext

Writing /home/zhouyu/.local/lib/python2.7/site-packages/pyDemFoam-2016.06.09.egg-info

However, when running 'python -c "import pyDemFoam; print pyDemFoam.version"', it replies that：
Traceback (most recent call last):
File "", line 1, in

Looking forward to your helping very much.
Best regards

What is the reason for this problem? It is because of the file "itasca-2016.06.09"“ itasca.py "Is there an error in the content of? I really hope to get a reply.

When I ran the model using the demicofoam solver, I found that the pressure gradient of the fluid was always calculated to be zero.Has anyone encountered the same problem?

Dear Furtney
I met a problem when I tested the code "pfc3d700_console call pfc_dropTest1.py". I listed the error report as below.
I don't how to handle it. So I turn to you. Hope to hear from you.
Best wishes.

Hello,
While building pyDemFoam all the commands go well but at the end to test the working of pyDemFoam the command "python -c "import pyDemFoam; print(pyDemFoam.version)" gives following error
"Traceback (most recent call last):
File "", line 1, in
File "/home/mahwish/.local/lib/python2.7/site-packages/pyDemFoam/init.py", line 3, in

Kindly guide me to resolve the error

Can we couple the PFC3D 7.0 with COMSOL v6.1?
I heard that we can use MATLAB in this case.
is there any code or example in this case?

An error occurred during the final step of verifying the compilation feasibility.
python -c "import pyDemFoam; print(pyDemFoam.version)"

Is there a version of OpenFOAM 7 solvers available？

Hello, thank you very much for providing the OpenFOAM--PFC coupling package. I encountered a problem in the process of using it.
The error message is： [Errno 111] Connection refused
looking forward to your reply！

When I build the pydemfoam, the error is as follows：

And my python-dev is the latest version. So how can I solve this problem?
Thanks a lot.

Hi,
I am just wondering why in sending body force data, yiu used:
((ca.drag().T/element_volume).T/fluid_density)
I didn't get the reason of "fluid_density"

Can we couple the PFC3D 5.0 with OpenFOAM v2112?
