Checking the Model

We advise that you perform a check before computing a case.

This task lets you know how to check whether specification assigned to a model are consistent. You can perform check operations on:

	Bodies
	Connections
	Others

Note that this check on features considered as inconsistent is performed both via the dialog box (one line per feature and a dedicated diagnostic box) and via highlighted associated features in the specification tree.

Check on Bodies

Check on bodies means on all the Mesh parts (1D, 2D, 3D) as well as their properties and supports.

Scenario1: You created a new property

For this, you selected the Solid Property command and selected pad1.

Open sample37.CATAnalysis document.

1. Click the Model Check icon

from the Model Manager toolbar.

The Model Check dialog box appears with the following tabs:

	`Bodies`: the lists of all the Mesh parts (1D, 2D, 3D) as well as their properties and supports.
	`Connections`: any connection specification
	`Others`: specification features (loads, restraints, virtual parts)

The Model Check dialog box displays all the parts (one per line in the dialog box) which are assigned at least one mesh part or property.

A status is assigned to each Mesh part you select in the dialog box, to let you know whether:

	you forgot to assign the material
	you assigned no or too many Mesh parts
	you assigned no or too many properties.

When you select a part in the table, the corresponding features in the specification tree and in the model as well as the assigned properties and material are also highlighted.

In this particular case, more than one property has been defined.

2. Click OK to leave the dialog box.

3. Delete the property you do not need and get this:

4. Click the Model Check icon from the Model Manager toolbar.

The specifications are now consistent: all the states are set to OK.

5. Click OK to leave the dialog box.

Scenario2: You deleted the material from an OCTREE mesh part

Open sample38.CATAnalysis document.

1. Click the Model Check icon

from the Model Manager toolbar.

The Model Check dialog box appears with the following tabs:

	`Bodies`: the lists of all the Mesh parts (1D, 2D, 3D) as well as their properties and supports.
	`Connections`: any connection specification
	`Others`: specification features (loads, restraints, virtual parts)

The Model Check dialog box displqys the lists of all the Mesh parts as well as their properties and supports.

A status is assigned to each Mesh part to let you know whether:

	you forgot to assign the material
	you assigned no or too many Mesh parts
	you assigned no or too many properties.

When you select a part in the table, the corresponding features in the specification tree and in the model as well as the assigned properties and material are also highlighted.

In this particular case, No Mesh Part is defined

2. Click OK to leave the dialog box.

3. Create a mesh part applied on PartBody of Part1.3 and get this:

4. Click the Model Check icon from the Model Manager toolbar.

The specifications are now consistent: all the states are set to OK.

5. Click OK to leave the dialog box.

Check on Connections

Check on connections means on any connection specification. In other words, you will check the consistency of the connections regarding the following: missing mesh parts, properties, materials ; connected supports with no associated mesh parts ; overlapping connections and so forth.

Scenario: You deleted the mesh part of a part that was connected to another

Open sample50.CATAnalysis document.

1. Click the Model Check icon

from the Model Manager toolbar.

The Model Check dialog box appears with the following tabs:

	`Bodies`: the lists of all the Mesh parts (1D, 2D, 3D) as well as their properties and supports.
	`Connections`: any connection specification
	`Others`: specification features (loads, restraints, virtual parts)

The Model Check dialog box and Connection tab display all the parts (one per line in the dialog box) which are assigned at least one connection:

	Mesh part and property assigned to this mesh part
	Connected mesh part
	Product to which the constraints was assigned
	Names of both mesh parts connected to each others
	Material (has no impact on Connection valid state).

When you select a connected mesh part in the table, the corresponding features in the specification tree and in the model as well as the assigned properties, material and constraints are also highlighted.

In this particular case, Face does not have a Mesh Part defined on it.

2. Click OK to leave the dialog box.

3. Create mesh parts on the geometry.

Check on Others

Check on others means on specification features such as loads, restraints, virtual parts, masses and periodic conditions.

Scenario: You deleted the mesh part of a clamped part that was connected to another

Open sample50.CATAnalysis document.

1. Click the Model Check icon

from the Model Manager toolbar.

The Model Check dialog box appears with the following tabs:

	`Bodies`: the lists of all the Mesh parts (1D, 2D, 3D) as well as their properties and supports.
	`Connections`: any connection specification
	`Others`: specification features (loads, restraints, virtual parts)

2. Delete OCTREE Tetrahedron Mesh.1 : Part1.1 feature in the specification tree.

The Model Check dialog box and Others tab display all the specifications features (one per line in the dialog box) which are not correct as well as details on the status of the selected line. In this particular case, Clamp1 is KO as the part the clamp was assigned to has been deleted.

In this particular case, the root design feature is no more support of any Mesh specification for Clamp.1 and Clamp.2.

2. Click OK to leave the dialog box.

The solution is therefore to add the mesh part to the invalidated part.
