Grid1D, Grid2D, Grid3D
Create a dataset that can evaluate 1D, 2D, or 3D functions or other datasets on a domain with a grid. For example, you can use these datasets to evaluate BEM and far-field operators.
Syntax
model.result().dataset().create(<dtag>,"Grid1D");
model.result().dataset().create(<dtag>,"Grid2D");
model.result().dataset().create(<dtag>,"Grid3D");
model.result().dataset(<dtag>).set(property,<value>);
Description
model.result().dataset().create(<dtag>,"Grid1D") creates a 1D grid dataset feature named <dtag>.
This dataset provides support for evaluation of functions or other datasets on a domain with a grid. All functions in the same function list as the selected function can also be evaluated. The domain is an interval for Grid1D, a rectangle for Grid2D, and a block for Grid3D. The domain does not need to have the same dimension as the number of arguments to the function.
The following properties are available:

Description
adaptive
true | false
true
For Grid1D only. If active, it can downsample 1D datasets by removing unnecessary evaluation points to improve graph plots.
data
none | dataset tag
none
The dataset this feature refers to.
distribution
uniform | exponential | mixed
uniform
The point distribution: uniform, exponential, or mixed uniform/exponential.
function
none | all | function tag
none
The function this feature refers to.
pari
String
Model dependent
The name of the parameter. par1, par2, and par3 for Grid3D, for example.
parmin1
double
0
Lower bound for the first dimension of the domain.
parmax1
double
1
Upper bound for the first dimension of the domain.
parmin2
double
0
Lower bound for the second dimension of the domain. (For Grid2D and Grid3D.)
parmax2
double
1
Upper bound for the second dimension of the domain. (For Grid2D and Grid3D.)
parmin3
double
0
Lower bound for the third dimension of the domain. (For Grid3D.)
parmax3
double
1
Upper bound for the third dimension of the domain. (For Grid3D.)
resi
integer >= 2
1000 for 1D, 100 for 2D, and 30 for 3D
The number of points into which each dimension is discretized. res1, res2, and res3 for Grid 3D, for example.
