Model exhaust air removal between glazing and air-permeable interior roller blind

[christoph-maurer]

In #144 , @vidanovic @simon-wacker and @christoph-maurer have implemented the option to define a constant forced convection in a gap. This serves well for exhaust air removal between a glazing and an interior roller blind which is not permeable for air.

As discussed with @dccurcija and @vidanovic , Fraunhofer ISE wants to develop a model for exhaust air removal between a glazing and an air-permeable interior roller blind. A thermal-pneumatic network needs to be developed to determine the air flow through the blind and the vertical distribution of the temperatures in the gap and the blind. For this network, we probably need a very good solver. Therefore, the Ceres solver is planned to be integrated in #171 .

@christoph-maurer Having additional solver is great for us. However, in order for this to be accepted in WCE main branch, it must compile and work under Windows, MacOS and Ubuntu. You can actually see that automated tests are already set up. Second thing is that external projects should be added through CMake. For example, WCE is using GTest as external project:

Windows-CalcEngine/CMakeLists.txt

Lines 66 to 88 in 3929d68

	if( DOWNLOAD_GTEST STREQUAL ON ) # Do not need gtest since it will be processed by E+
	# include(CMakeLists-GTest.txt)
	configure_file(CMakeLists.txt.in ${CMAKE_CURRENT_BINARY_DIR}/googletest-download/CMakeLists.txt)
	execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
	WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
	execute_process(COMMAND ${CMAKE_COMMAND} --build .
	WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
	# Prevent GoogleTest from overriding our compiler/linker options
	# when building with Visual Studio
	set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
	# Add googletest directly to our build. This adds
	# the following targets: gtest, gtest_main, gmock
	# and gmock_main
	add_subdirectory(${CMAKE_CURRENT_BINARY_DIR}/googletest-src
	${CMAKE_CURRENT_BINARY_DIR}/googletest-build)
	# Now simply link your own targets against gtest, gmock,
	# etc. as appropriate
	include_directories( ${CMAKE_CURRENT_BINARY_DIR}/googletest-src/include )
	endif ()

I have another project where I use eigen as externa project:
https://github.com/LBNL-ETA/HygroThermFEM
Question for @RDmitchell and @dccurcija if it is ok to give @christoph-maurer and @simon-wacker access to HygroThermFem (https://github.com/LBNL-ETA/HygroThermFEM) so they can see an example on how is that done there?

It seem that ceres also have github:
