Data Names Introduce

   The following is about data names (Data Names) My introduction comes from HM help .

   Data name （Data Names） It can be used for Queries and operations HM Details of core data in .

   Template file (Template files ) and Tcl The command uses a data name to access HyperMesh Information in the database . The data name is a string representing data .

   At output time , The solver template replaces the data name string with the value represented by the data name . for example , A node has ID、x、y、z and system As a possible data name . If you enter the command in the template file *field(integer,id,8), be HyperMesh With 8 Output node in integer form of spaces id. These data names can also be used through Tcl Inquire about , Example: by command :hm_getvalue nodes id=$id dataname=x Query the x coordinate .

   Data name （A data name） It can also represent a pointer to another entity in the database . For units （element）, Data name node1 It's a pointer .node1 Point to HyperMesh A node in the database . If you enter a command *field(integer,node1,8), HyperMesh An error message will be sent , be HyperMesh Unable to output the correct value , because node1 Point to a node entity with many different printable values . To print nodes ID, Reference the pointer as *field(integer,node1.id,8). Use the dot （.） As a separator, the data name node1 And data name ID Separate . Corresponding Tcl The order is hm_getvalue elems ID =$ID dataname=node1. ID.

   data ( Except for global data ) Only at the template level 2（levels two） To 4（levels four） Available in the . The way to reference all pointers is to add a period after the name （.）, Followed by the data name of the entity type . It is important to note that , Some data names can only be used through Tcl Inquire about , You cannot query through the template system .

The following entity types have data names （Data names）:

Data name （Data Names） Use

   Check those HM The data names of entity objects , Can be in hm The directory of help documents is as follows hm_ref_guide/topics/reference/hm/ The query under the location has data_names- Enter the beginning htm file , Or search directly on the help page Data Names, for example HyperMesh2017 Of Data Names Enquiries are as follows ：
   Click on Data Names In the help page HM The entity list can query the data name of the entity object , for example , Components (components） The data name ：
   Use the Data Names, We can query and modify the corresponding parameter values .

Create entities （Entity） When using Data Names

   The following code creates a file named new, Components in red .

*createentity comps name="new"  color=3

Set entity （Entity） Parameter values for

   The following code will id by 1 The material of the component of is modified to id=2 The material of .

*setvalue comps id=1 STATUS=2 materialid={mats 2}

   Be careful ： For some of the entity objects Data Name When the value of is too much , use *setvalue Settings will not work . for example , For settings Set When an element of an object , When there are too many nodes or grids, it cannot be used *setvalue Set up , Instead, its parameters are defined at the time of creation , as follows ：

*createentity sets type=nodes ids={1 2 3 4}

Get entities （Entity） Parameter values for

   Obtained by the following code id by 1 Materials of components id.

hm_getvalue comps id=1 dataname=materialid
