itasca.cfdarray

Array interface for CFD.

Functions

itasca.cfdarray.create_mesh(nodes: array float{nnodes, 3}, elements: array int{nelem, 8}) None.

Create a cfd mesh. The indices in the array elem should index the node locations in the array node. Counting begins at 0.

itasca.cfdarray.density() array float{element}.

Get a numpy array of the cfd element fluid density.

itasca.cfdarray.drag() array float{3,element}.

Get a numpy array of the cfd element fluid drag force.

itasca.cfdarray.extra(slot: int) array float{CFD element} or float{CFD element,3}.

Get the CFD element extra data in the given slot as an array. Extra variables accessed by array must be of type float or vec.

itasca.cfdarray.fill_pos(data: array float{CFD element, 3}) None.

Fill an existing array with the CFD element centroid location. The array must be the correct shape.

itasca.cfdarray.fill_pressure(data: array float{element}) None.

Fill an existing array with the cfd element fluid pressure. The array must be the correct shape.

itasca.cfdarray.ids() array int{CFD element}.

Get the CFD element ids as an array.

itasca.cfdarray.porosity() array float{element}.

Get a numpy array of the cfd element fluid porosity.

itasca.cfdarray.pos() array float{CFD element,3}.

Get a numpy array of the CFD element centroid location.

itasca.cfdarray.pressure() array float{element}.

Get a numpy array of the cfd element fluid pressure.

itasca.cfdarray.pressure_gradient() array float{3,element}.
