create/src/Mod/Material/FluidMaterial

FreeCAD fluid material library

It's intended to gather the most common fluid properties, water, air, which are useful for other modules and workbenches.

User defined material

To prevent the database from becoming inefficiently large it is only limited to commonly used variables at 20 degrees Celsius at 1 atm.

Users can defined new material, either in Fem material card editor, or directly generate textual material file, * .FCMat, see example in this folder.

To enable new material, go to FreeCAD menu "Edit->Preference..." Cfd preference page (select on the left panel) and switch to materiai tab on the right.

Browse to your material folder, and save/apply this preference, new material will be Material with same name as FreeCAD material has higher priority, so user defined Water material will not appear in Fem material task panel's dropbox list, just give it a different name!

Edit material value

Please verify the fluid material properties before use. It aims to serve as a quick reference and does not aim to be an extended look up table.

Add new material to Material module

1. follow examples in material folders to create new material file
2. stick to the meta data definition in src/Mod/Material/Templatematerial.yml for property name
3. add the file name into the src/Mod/Material/CMakeLists.txt , so the new files can be installed to the properly place during compiling and installation.
