Refactor Units making it constexpr, immutable, with repetition reduced.
Separate data from code.
Constexpr constructed units allow constructing predefined Quantities
from predefined unit types.
Dimensionless quantities have all exponents equal to zero.
Such quantities are simply numbers. The associated unit is
the unit one, symbol 1, although this is rarely explicitly
written.
See chapter 2.3.3 Dimensions of quantities, The International
System of Units, 9th edition.
Quantity is often queried for Unit just to see if it has a dimension.
Ask Quantity directly using isDimensionless() method and modify that
method not to care about Quantity value validity; no user was ever
asking for value validity.
Fixes: Maintaining schemas is difficult and error-prone
- Facilitate easy schemas add, remove, change, etc.
- Remove 14 files containing approx 2,190 lines of if/else code and data
- Place data in one file (UnitsSchemasData.h) using a normalized structure (including special functions)
- Isolate and simplify data operations (code)
- Remove schemas enum to keep data independent of code
- Separate responsibilities: Specifications, data, schemas, schema
- Add schema data 'isDefault'
- Add schema data name
- Prefer algorithms to raw loops
- Add schemas unit tests
- Tweak quantity unit tests
Rename files according 7d233dc ("Gui: Rename generated lexer files
to match core naming pattern"). Note that C space errors (space
before tabs, spaces on blank lines, etc.) still need to be fixed
manually after regenerating lexer file.
If an exception is thrown then the allocated buffer won't be cleaned up. To make this exception-safe the class
StringBufferCleaner is added using the RAII idiom
Adds a few new Expression functions with the goal to:
- Simplify Placement, Rotation, Vector and Matrix object creation.
- Add new matrix functions for rotation and translation.
- is not feasible for practical usage and (was up to now not used, thus no consequence)
moreover, Oersted is a cgs unit while we use SI units, thus also not suitable for FEM, only makes problems for magnetization
* ignore -Wfree-nonheap-object for generated code
* replace 0 with Qt::NoModifier when creating a QKeyEvent
* in Qt 5.14 QCombobox::activated(QString) is deprecated, use textActivated
* don't mix QCheckBox::setChecked() with tristate API
- this is necessary to perform electrodynamics simulations. Since the typical values are in the range of 1e6 S/m, we need the new units kS and MS
- since this is for simulations, also add electrical conductivity to the FEM material cards
