Hello,
I use mfix-21.4and I want to run the case Absorption in the tutorial. However, when I built the solver by 
button in GUI, it reported error:
This is old cmake_args
[’-DMPI_Fortran_COMPILER=mpiifort’, ‘-DENABLE_PYMFIX=ON’, ‘-DPython3_EXECUTABLE=/ncsfs02/bychen/anaconda3/envs/mfix-21.4/bin/python3.8’, ‘-DPython3_ROOT_DIR=/ncsfs02/bychen/anaconda3/envs/mfix-21.4’, ‘-DENABLE_MPI=1’]
new cmake_args has been changed to:
[’-DMPI_Fortran_COMPILER=mpiifort’, ‘-DENABLE_PYMFIX=ON’, ‘-DPython3_EXECUTABLE=/ncsfs02/bychen/anaconda3/envs/mfix-21.4/bin/python3.8’, ‘-DPython3_ROOT_DIR=/ncsfs02/bychen/anaconda3/envs/mfix-21.4’, ‘-DENABLE_MPI=1’, ‘-DMPI_C_COMPILER=/opt/intel/impi/4.1.1.036/intel64/bin/mpicc’, ‘-DMPI_CXX_COMPILER=/opt/intel/impi/4.1.1.036/intel64/bin/mpicxx’]
