XML Mapping File

To be valid, the XML mapping file requires the following elements:

<?xml version="1.0" encoding="UTF-8"?>
<ListOfProperties xmlns="urn:propertymappingrules" 
xmlns:xsl="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="urn:propertymapping rules PropertyMappingRules.xsd">

<!--   file content   -->

</ListOfProperties>

The decimal point used in the exported XML mapping file depends on the regional settings of your operating system. It can be either a period or a comma (for example: 0.001 or 0,0001). No other symbol is supported; a warning message is displayed when you update the property if the decimal point used in the XML file does not correspond to the regional settings of your operating system. The name of the .xsd file also depends on the regional settings of your operating system:

• If the decimal point is a period, the .xsd file name must be PropertyMappingRules.xsd.
• If the decimal point is a comma, the .xsd file name must be PropertyMappingRules-fr.xsd.

Default Values

DEFAULT_VALUES is the keyword that specifies and defines the default tolerance and the default axis system.

Units

UNITS is the keyword you that specifies the default units.

Note: The syntax of the units is the same as specified in the unit settings Tools > Options > Parameters and Measure > Units.

Spatial Identification

The spatial identification is based on the coordinates (X, Y, Z) of the geometric center of finite elements. Use the spatial identification when more than one element is bounded by four geometries.

You can also specify an optional tolerance value to capture the element that is the closest to the specified coordinates in the given tolerance (TOL).

Associative Identification

The associative identification is based on geometric reference path in the specification tree and allows you to capture elements that belong to a mesh, to a group, and to a geometry. You can also refine the element selection by identifying elements that share nodes with a mesh, a group, or a geometry.

Notes:

• You cannot use the SHARE_WITH criterion as the only associative identification. It is used to filter of the result of a BELONG_TO identification.
• You cannot use the BELONG_TO_GEOM keyword in the solid property definition.
• If no element is found, a warning message will be displayed when you update the property.

To identify geometries, use the specification tree path as follows: from the product where the finite element model representation is instanciated down to the geometry you want to identify, write the name of each feature and separate them using the \ character.

To identify publications, use the specification tree path from the product where the finite element model representation is instanciated up to the product instance that contains the publication of the geometry as shown below:

Name of the product\Publications:Name of the published element

Consider the following specification tree structure:

The Extrude.1 geometry is identified as follow:

BELONG_TO_GEOM="MyProduct001\My3DShape001\PartBody\Extrude.1"

The Extrude1_Pub publication is identified as follow:

BELONG_TO_GEOM="MyProduct001\Publications:Extrude1_Pub"

For finite elements on which you want to apply the same property with the same characteristics, you can use identification by intersection or identification by union, but you cannot mix the both identifications in the same keyword.

Identification by Intersection

You can use intersection of geometries or groups to identify finite elements inside the same keyword by separating geometries, meshes, or groups using the ; symbol (no space around the ; symbol). The result of the selection is the intersection of all the selected geometries, meshes, or groups.

You can also use the intersection by combining the BELONG_TO and SHARE_WITH keywords to refine your selection. This combination is possible if each keyword appears only once per XML line. The result of the selection is the intersection of each keyword results. For example:

• The following identification:

  BELONG_TO_GEOM="Fill.1;Fill.2" SHARE_WITH_GROUP="Group.2"

  means that you will first capture elements that belong to the intersection of Fill.1 and Fill.2 geometries and then filter the captured elements with elements that share at least one node with the Group.2 group.
• Consider the Fill.1 geometry meshed with four frames (F1, F2, F3, F4) as constraints and the automatic capture mode:
  
  

  BELONG_TO_GEOM="Fill.1" SHARE_WITH_GEOM="F1;F2;F3;F4"

  means that the defined property is applied to the elements that belong to the Fill.1 geometry and that share nodes with the frames F1, F2, F3, F4. E1 is the only element that satisfies those conditions.

Identification by Union

You can use union of geometries, meshs or groups to identify finite elements inside the same keyword by separating geometries, meshes, or groups using the + symbol (you can add a space around the + symbol). The result of the selection is the union of all the selected geometries, meshes, or groups.

Important: The union is possible only for the BELONG_TO_GEOM, BELONG_TO_MP and BELONG_TO keywords.

The line:

<SHELL BELONG_TO_GEOM="Fill.1+Fill.2" TH="0.5" MAT="Material.1"/>

is equivalent to the two following lines:

<SHELL BELONG_TO_GEOM="Fill.1" TH="0.5" MAT="Material.1"/>
<SHELL BELONG_TO_GEOM="Fill.2" TH="0.5" MAT="Material.1"/>

Beam Property

BEAM is the keyword you have to use to apply a beam property.

Tip: To find the start node and the end node and to visualize the implicit orientation of 1D elements imposed by the mesh, generate a Local axis image. The X-direction determines the start node, and the end node is determined as shown below:

Variable Beam Property

BEAM_V is the keyword you have to use to apply a variable beam property.

Tip: To find the start node and the end node and to visualize the implicit orientation of 1D elements imposed by the mesh, generate a Local axis image. The X-direction determines the start node, and the end node is determined as shown below:
