Curves
define curves in the input file
In
MESHFREE, curves are tables of values that can be used to assign any physical or geometrical quantity,
such as density depending on pressure or viscosity depending on temperature. They are defined in a
begin_curve{ environment.
We distinguish between
1D_Curves and
2D_Curves, for details see there.
Once a curve is defined, it can be used in a
RightHandSideExpression, e.g. in a boundary condition:
Or within equations:
[ ... curve($CurveName$) ... ]
They return linearly interpolated values between the given interpolation points.
