Type

HyperMesh Tcl Query Command

Description

Queries data names, attributes, and metadata on entities. It will return the value of any type of data name, attribute, or metadata of an entity. In addition, this command will also return the value at a specific index for array type of data names, attributes, and metadata.

Inputs

entity_type

The type of entity to query.

<select_type>=<selection>

The entity or entities that are to be queried. There are several ways to provide the entities to be queried. Only one option can be used at a time:

id=<id>: The ID of the single entity to query.
name=<name>: The name of the single entity to query.
mark=<mark_id>: The ID of the mark containing the entities to query.
list=<list_id>: The ID of the list containing the entities to query.
user_ids={<id1> <id2> ... <idN>}: The IDs of one or more entities to query.
user_names={<name1> <name2> ... <nameN>}: The names of one or more entities to query.

dataname=<data name or attribute name/ID>

The dataname=value data name and/or attribute pair that defines the relevant data to query. For attributes, this can be either the attribute name or ID. If not specified, one of the metadata_value... options must be used.

column=<column_index>

This is the optional column index for a 2D array. Used together with row_index, it returns the value at the specified row_index and column_index.

locationunit={<entity_id>, <face_index>}

Valid only for engineering loads. This is required if a non-uniform load is being queried. If the load is applied on a regular set, only <entity_id> is needed. If the load is applied on solid element faces, then <face_index> is also required.

entity_id: The ID of the entity to query.
face_index: The index of the solid element face.

metadata_value=<metadata_name>

This is to query the metadata value for a specified metadata name. This is valid for all types of metadata.

metadata_value_count=<metadata_name>

This is to query the metadata count for a specified metadata name. This is valid for all types of metadata.

metadata_value_ids=<metadata_name>

This is to query the metadata entity IDs for a specified metadata name. This is valid for entity and entity array metadata.

metadata_value_type=<metadata_name>

This is to query the metadata entity type for a specified metadata name. This is valid for entity and entity array metadata.

modelname=<name_of_model>

This is the optional model name to query when there are multiple models in the database. If not specified, the current model is used.

row=<row_index>

This is the optional row index for a 1D or 2D array. For 1D array, it returns the single value at the specified index. For a 2D array, it will return the entire row.

Examples

Get the node IDs in a set named node_set:

hm_getvalue sets name=node_set dataname=ids

Get the name of entity set with ID 1:

hm_getvalue sets id=1 dataname=name

Get the attribute Rho of material ID 1:

hm_getvalue mats id=1 dataname=Rho

Get the attribute 183 of material ID 1:

hm_getvalue mats id=1 dataname=183

Get materialid for components on mark 1:

hm_getvalue comps mark=1 dataname=materialid

Get node1 for elements 1 and 2 on list 1:

hm_getvalue elems list=1 dataname=node1

Get materialid for components with names "mid" and "center":

hm_getvalue comps user_names={mid center} dataname=materialid

Get submodel types for include file 10:

hm_getvalue includes id=10 dataname=typesundersubmodel

Get the attribute Rho of material ID 1 for model model-2:

hm_getvalue mats id=1 dataname=Rho modelname=model-2

Get a magnitude value for non-uniform distributed load 5 on node 15:

hm_getvalue loads id=5 dataname=magnitude locationunit={15}

Get a magnitude value for non-uniform distributed load 5 on element 25 face 2:

hm_getvalue loads id=5 dataname=magnitude locationunit={25,2}

Get the metadata value for an integer metadata with the name mymeta_int on a component:

hm_getvalue comps id=1 metadata_value=mymeta_int

Get the metadata value for an entity metadata with the name mymeta_entity on a component:

hm_getvalue comps id=1 metadata_value=mymeta_entity

Get the metadata value entity count for an entity array metadata with the name mymeta_entityarray on a component:

hm_getvalue comps id=1 metadata_value_count=mymeta_entityarray

Get the metadata value entity IDs for an entity array metadata with the name mymeta_entityarray on a component:

hm_getvalue comps id=1 metadata_value_ids=mymeta_entityarray

Get the metadata value entity types for an entity array metadata with the name mymeta_entityarray on a component:

hm_getvalue comps id=1 metadata_value_type=mymeta_entityarray

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
