hm_getmidsurfaceinfo

Returns information related to geometric midsurfaces.

Syntax

hm_getmidsurfaceinfo query_type=<value> input_mark=<mark_id> ?<option1>=<value1>? ?<option2>=<value2>? ... ?<optionN>=<valueN>?

HyperMesh Tcl Query Command

Returns information related to geometric midsurfaces.

query_type=<value>: The type of query to perform:; find_midsurface - Finds midsurfaces corresponding to input_entity_type comps, surfs or solids. The return is the list of output_entity_type IDs.; find_parent_geometry - Finds comps, surfs or solids corresponding to input_entity_type midsurfaces. The return is the list of output_entity_type IDs.; is_midsurface - Checks if a given input_entity_type of comps or surfs consists of midsurfaces only, non-midsurfaces only, or both. The return is yes, no or mixed.
input_mark=<value>: The ID of the mark of input entities. Valid values are 1 and 2.
input_entity_type=<value>: The type of input entity on input_mark. Valid values are given in query_type. If there is only one possible value, this can be omitted.
output_entity_type=<value>: The type of output entity. Valid values are given in query_type. If there is only one possible value, this can be omitted.

To get the list of middle surfaces corresponding to solid with ID 19:

*createmark solids 1 19
hm_getmidsurfaceinfo query_type=find_midsurface input_mark=1 input_entity_type=solids

To get the component containing the original geometry for the middle surface with ID 19:

*createmark surfs 1 19
hm_getmidsurfaceinfo query_type=find_parent_geometry input_mark=1 input_entity_type=comps

To see if the surface with ID 19 is a midsurface:

*createmark surfs 1 19
hm_getmidsurfaceinfo query_type=is_midsurface input_mark=1

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

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