Installation on windows using Visual C++ compiler
Hello,
I downloaded the sfepy source code from git and installed it using the Visual C++ compiler. After installing, I ran the tests and 4 of them failed. I then ran those tests in debug mode and the output is attached. Please tell me how to solve this problem.
Best regards, Nikhil
Hi Nikhil,
to resolve test_projections and test_input_navier_stokes2d_iga, install igakit [1]. But note that it is not needed when using sfepy for finite element computations. You may want igakit only when playing with the isogeometric analysis computations.
The other two errors are related to use of multiprocessing when computing homogenized coefficients  I am not sure why that happens. What version of python/multiprocessing do you use?
As a workaround you can try adding
'multiprocessing' : False,
into options dicts in examples/homogenization/perfusion_micro.py and examples/homogenization/linear_elastic_mM.py.

thanks for your reply. the version of python/multiprocessing is 0.70a1
For now, I will proceed with the workaround.

the workaround suggested by you solves the problem with the homogenization_perfusion test but not with the input_linear_elastic_mM test.

Yes, my bad  you need to add the "'multiprocessing' : False," option into options in linear_homogenization_up.py file  this is the microproblem used by input_linear_elastic_mM.

Thanks! that solves the problem.
A question about the workaround.... Does it mean that I can use sfepy now without any problems if I do not use multiprocessing in the homogenization coefficients calculation?
