with <args>: num ?line_uv <line_index> | index_boundaries | has_holes | render_mesh | mesh | material?
line_uv <line_index> extra arguments must be only used in case of nurbs surfaces, to get the information of the <line_index> curve (integer from 1 to the number of trimming curves) on the surface, defined in its uv space parameter.
index_boundaries extra argument to get an objarray of integers with the index of the list of curves where each boundary start.
If the surface doesn't has any hole, it return 0 (the start index of the outer loop)
It the surface has holes it return an index by hole (the start index or the hole inner loop)
has_holes: it return 0 if the surface doesn't has any hole, 1 else
-v2 mean version 2 of this command and then return this data (deprecated version 1 documentation must be seen in help of old versions of the program)
...
Will return the information of the mesh of the geometric entity <id> as a list: {element_type element_num_nodes node_ids coordinates element_ids connectivities ?radius_and_normals?}
element_type: string
element_num_nodes: integer with the amount of nodes of an element (all mesh elements are of same type)
node_ids: objarray of integers with num_nodes items, where num_nodes is the amount of nodes of the elements of this mesh (node id one-based)
coordinates: objarray with 3*num_nodes items of double with x y z of the mesh nodes.
element_ids: objarray of integers with num_elements items (element id one-based)
connectivities: objarray with element_num_nodes*num_elements of int with the connectivities of the elements (one-based)
radius_and_normals: only for sphere and circle elements. objarray with num_elements items of double with the radius of each element or num_elements*4 items for circles, with the radius and the normal 3D vector (normal to the plane of the circle).
- GiD_Geometry get point|line|surface|volume <id> material
Will return an integer with its material index
list: to get a list of entity identifiers of a range or inside some layer
...
<filter_flags> could be: ?-unrendered? ?-higherentity <num_higher>? ?-material <id_material>? ?-layer <layer_name>? ?-plane {a b c d r}?
-unrendered flag is only valid for surface
-higherentity <num_higher> to filter the selection and list only the entities with the amount of parents equal to <num_higher> (integer >=0)
-material <id_material>to filter the selection and list only the entities with material id equal to <id_material> (integer >=0)
-plane <a b c d r> to list only the entities wigth center that match the plane equation a*x+b*y+c*z+d<=r
-entity_type <types_allowed> to list only the entities of a type contained in <types_allowed>, that must be a list of allowed types ("STLINE | ARCLINE |POLYLINE | NURBLINE | NURBSURFACE PLSURFACE COONSURFACE MESHSURFACE CONTACTSURFACE VOLUME CONTACTVOLUME")
<args>: <num>|<num_min>:<num_max>
<num_max> could be 'end' to mean the last index
if <args> is not provided it is considered as 1:end, and then all ids are returned
Examples:Creation of a new NURBS surface:
GiD_Geometry create surface 1 nurbssurface Layer0 0 {1 4 3 2} {1 1 1 1} \
{1 1 2 2 {0.17799 6.860841 0.0 -8.43042200 6.86084199 0.0 0.17799400 0.938510 0.0 -8.43042 0.938510 0.0} \
{} {0.0 0.0 1.0 1.0} {0.0 0.0 1.0 1.0}}
Get the list of points of the layer named 'Layer0':
GiD_Geometry list -layer Layer0 point
Get the list of surfaces that not belong to any volume:
GiD_Geometry list -higherentity 0 surface 1:end
Get the list of problematic surfaces that couldn't be rendered:
GiD_Geometry list -unrendered surface 1:end
Get the list of lines of type nurbline or arcline
GiD_Geometry list -entity_type {nurbline arcline} line
