Inline functions

These are wrapped versions of inline APDL functions that perform operations like finding the x-coordinate of a node given its number (Query.nx).

class ansys.mapdl.core.inline_functions.Query(mapdl)

Class containing all the inline functions of APDL.

Most of the results of these methods are shortcuts for specific combinations of arguments supplied to ansys.mapdl.core.Mapdl.get().

Currently implemented functions:

Examples

In this example we construct a solid box and mesh it. Then we use the Query methods nx, ny, and nz to find the cartesian coordinates of the first node. We can access these through the mapdl.queries property.

>>> from ansys.mapdl.core import launch_mapdl
>>> mapdl = launch_mapdl()
>>> mapdl.prep7()
>>> mapdl.et(1, 'SOLID5')
>>> mapdl.block(0, 10, 0, 20, 0, 30)
>>> mapdl.esize(2)
>>> mapdl.vmesh('ALL')
>>> q = mapdl.queries
>>> q.nx(1), q.ny(1), q.nz(1)
0.0 20.0 0.0
