Checking your finite element model

Video: Check element quality

You can use several commands to validate your model. You can use these commands to:

• Check how well the model’s CAE geometry conforms to the underlying CAD geometry.

• Ensure the quality and consistency of your mesh.

• Validate that the model is complete and ready to solve.

The following table summarizes the available commands.

Command	Icon	Description	Additional information
Element Quality		Lets you evaluate the quality of elements in your model based on both general and solver-specific criteria.	Evaluating element quality
Element Edges		Lets you display any 2D and 3D elements with free edges. Also lets you display any non-manifold element edges.	Checking for free and non-manifold element edges
2D Element Normals		Lets you evaluate the consistency of the 2D element normals in your model.	Checking and orienting the normals of 2D elements
3D Element Face Normals		Lets you evaluate the consistency of the 3D element normals in your model.	Checking and orienting the normals of 3D element faces
Duplicate Nodes		Lets you check your model for duplicate nodes and merge any of those nodes together.	Checking for duplicate elements and nodes
Duplicate Elements		Lets you check your model for duplicate elements and delete any of those duplicates.	Checking for duplicate elements and nodes
Element Material Orientation		Lets you display the material orientation of 2D and 3D elements in your model.	Displaying an element’s material orientation
Adjust Node Proximity to CAD		Lets you adjust the proximity of nodes created on polygon geometry to the underlying CAD geometry.	Controlling the proximity of nodes to the CAD Geometry
CAE Model Consistency		Lets you evaluate the polygon geometry in your model for consistency issues.	Checking CAE model consistency
Detect Interference/Clearance		Lets you detect regions of interference within your model.	Detecting interference and clearance issues between faces
Solid Properties Check		Calculates the solid properties of the finite element model.
Check Association		Lets you verify that the nodes in your model are associated to the underlying geometry.	Checking the association of nodes to geometry
Finite Element Model Summary		Lets you print an informational summary of the entities in your FEM file.
Simulation Summary		Lets you print an informational summary of the entities in your Simulation file.
Model Setup		Lets you evaluate whether your model is ready to solve.	Checking the completeness of your model prior to a solve
DOF Dependence Check		Lets you find and resolve double dependencies within your model.	DOF dependence check
