Three basic observations: 1. More variables (opposed to constants) to be calculated require more time 2. The difference between the Material law ML and User Law (UL) for density is in significant. 3. Biggest difference seems to be between all constant or not all constant. Maybe the call to external ...

Some numbers to chew. The case is the duct above where various parameters are either provided by CoolProp (ML) or constant (C) or - in case of density - by own formula (UL) - Bon appetit, and thank you for your being so helpful. ML = Material Law C = Constant UL = User Law (density = rho0*(293.15/te...

Below I summarize the fruit of my struggles as it may be of use to others. Parts of the method requires write access to system directories and should therefore be in a "sudo" shell. Download "CoolProp_sources.zip". I used this url: https://netix.dl.sourceforge.net/project/coolpro...

So I ended up with presenting the CoolProp library to the Code_Saturne installation by pursuing my first approach of introducing the libraries and header files into the standard system tree, more specific in /usr/local/lib (library) and /usr/local/include (header). This way the installation process ...

I now have built the CoolProp library locally from source, and ./configure now seems to pass tests when issued manually with the "--with-coolprop=/opt/coolprop" option. Next step will be to find out to integrate it into code_saturne to avoid this error: configure:12913: checking for CoolPr...

Thank you again, Yvan. Output from configure. Using Coolprop 6.5 I get a few warning which may or may not be of importance: configure:12932: gcc -o conftest -funsigned-char -W -Wall -Wshadow -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-d...

From "install_saturne.log" checking for CoolProp library)... no So this seems is a required prerequisite and not installed via the setup file ... I was not aware of that :? Apparently I can download the library from here: https://sourceforge.net/projects/coolprop/files/CoolProp/6.5.0/share...

Hello, I just built Code_Saturne Version 8.0.2. and notice the very nice feature of a material library. Thank you very much for that. A really convenient addition. I have started my first run, a gui case with water selected as fluid, But ... looking through the listing I see the following: field min...

Hello Yvan. Thank you for answering. As I wanted boundary layer meshing of the fluid I went with the fluid mesh as one sub-mesh and the solid as another submesh. After defining groups from geometry I saved the hdf, deleted one submesh and groups and exported. Then I reloaded the hdf and did similarl...
