This interface can be used to offset elements along average shell normals. The Copy Elements option will make a copy of the offset elements and retain the original elements in their initial state. Shell element normals for the selected elements are required to be consistent (shell normals can be checked and corrected using the Normals Interface).
This interface has variety of applications such as creating a punch part from a die in metal forming. Often shell parts are not meshed at their proper mid-surface. This can result in initial penetration conditions with adjacent parts. Offsetting shells provides a method of resolving such conflicts without having to remesh the part from scratch.

Purpose:
This interface provides a means to transform parts or selected elements from one coordinate system to another. Transformation is generally useful for positioning operations that require a combination of translation and rotation. The definition of a coordinate system requires 3 sets of coordinates. These can be input by selecting 3 nodes, keying in coordinates, or picking positions using the 'Create Position' sub-interface. The first set of 3 points defines a coordinate system for 'From' (the source position), and the second set of 3 points defines a coordinate system for 'To' (the target position).
By activating the Copy Elem option, the transformation is applied to a copy of the elements as opposed to the selected nodes. The selection of nodes to transform can be made various ways using the General Selection Interface, but in the end it is only the nodes that get transformed.
Function:
Transform Nodes : Transform selected nodes from one coordinate system to another coordinate system.

Uniformly aligned normals are also required before performing a shell offset operation.

Disjointed meshes are often due to mesh generation of sub-domains of a single part which result in free nodes along internal edges. The Show Free Edges toggle displays free edges on the mesh. Such disjointed situations can be detected by finding pairs of nodes that are within a certain tolerance distance of each other. These nodes can then be combined using the Merge Duplicate Nodes button. Upon merging nodes within the user specified tolerance, an option to retain the largest or smallest node ID is available.

This interface is used to make measurements of various aspects of the model and to create local coordinate systems. It is available for pre and post-processing phases. If an LS_DYNA keyword file or project file is loaded, measurements are limited to single values. If post-processing files are loaded, measured quantities wil be XY plotted.

This interface is for morphing of an existing mesh.
- Solid Cons
This method works by constraining the parts to be morphed (Morph nodes) within a solid hex mesh (Con. Ele.). Once Constrain has been activated, the hex mesh can be transformed in any way, and the Morph nodes will follow. The nodal coordinates are transformed based on their relative position within their containing solid element. Thus in order to make more precise adjustments, a finer solid mesh should be used.
- 8 Lines Cons
This method works by mapping the parts to be morphed between a set of 8 line (4 Source and 4 Target). It is similar to the first method except the solid mesh generation is done transparently and automatically.

Enter number of smoothing iterations before projecting nodes back to original mesh surface.
- Project back
Project nodes back to geometry.

Reject smoothing operation.

Accept smoothing operation.
- Done
Exit Smooth Interface.
This interface can be used to trim (cut) parts with curves. The target application for this function is to trim parts after a metal stamping operation but it can be useful for other purposes as well. Note that if stresses, strains, and thicknesses are available (typically from dynain files), then upon trimming this data is updated. Adaptive constraints are also handled in the trimming process.
- Parts
when active, parts to trim can be selected by clicking on them in the graphics window.
- Curves
when active, curves that should be used for the trim/cut operation can be selected by clicking on them in the graphics window.
- RefPlane
when active, pick reference plane on graphic area used for the trim operation.
- Keep
If the Keep radio button is active, no elements will be deleted or moved to another part.
- Delete
when active, one seed element should be picked. the elements that are topologically connected to the seed elements will be deleted after the trimming operation is performed.
- Move
when active, one seed element should be picked. the elements that are topologically connected to the seed elements will be moved to a new part after the trimming operation is acceptedt.
- Limit
Elements further away than this distance will not be trimmed.
- Tolerance
Nodes close to the trim curve will be moved to the cutting surface if they are closer than Tolerance*element_size. This prevents very small elements from being created on the cut line.
- Closest 3D proj dir.
The cutting surfaces are created from the curve definition and are extended in the normal direction of the closest element. This gives a cut on the selected parts as close as possible to the curve. This method is useful when the elements to be cut would be parallel or nearly parallel to the trim vector direction with the previous method. This method can, for example, trim the rubber cut line on a tennis ball, as shown in Figure 1, where the vector projection method would fail.
- Vector projection
The part(s) will be cut with cutting surfaces that are made from the curve and extruded the distance Limit in both positive and negative Vector direction.
- Vector
The general vector creation function can be activated.
- X/Y/Z
The vector direction is defined by the x, y, and z fields. X, Y, and Z buttons for quickly setting the vector to any of the global directions are also provided.
- Trim
The trim operation is executed.
- Reject
The trim operation can be rejected.
- Accept
The result will be displayed, and the trimmed elements can be kept.
- Done
Accepts the trim operation and exits the PTrim Interface.
This interface can be used to position the components involved in a forming siumlation (part, die, punch, blank, blank-holder, etc...) so that they are in exact contact at the beginning of the analysis.
Move a part reference to another part.
- Moving Parts
Select moving parts. The nodes of the Moving parts will be moved. Multiple parts can be selected.
- Fixed Parts
Select fixed parts. the Fixed parts acts like a contact surface. Multiple parts can be selected.
- Allow rotation
Select fixed parts. the Fixed parts acts like a contact surface. Multiple parts can be selected.
- Ref. node
The rotation point, which is the same as the reference point, can optionally be changed to be at any nodal position by activating the Ref. node toggle and picking a node with the left mouse button or typing a node ID in the text field. The stresses and strains on the *INITIAL_STRESS_SHELL, *INITIAL_STRAIN_SHELL, and *INITIAL_STRESS_SOLID keywords are automatically rotated to follow the rotation of the elements in the moving parts.
- T1
The thicknesses of the moving parts will be considered if the T1 toggle is active.
- T2
The thicknesses of the fixed parts will be considered if the T2 toggle is active.
- Gap
With either of these toggles active, an appropriate gap will be left between the moving and the fixed parts. The purpose for this is to make the parts "exactly in contact" as far as LS_DYNA is concerned. Additional clearance between the moving and the fixed parts can be added by typing a value in the Gap field.
- Direction
Popup direction dialog to define a vector.
- Flip Dir.
The direction of travel can be reversed.
- S2S check
Perform surface to surface check between parts.
