Basic Features

SUPPORTED QUANTITIES
- thickness (scalar)
- stress (tensor)
- strain(tensor)
- effective plastic strain (scalar)
- (History variables, young's modulus and others can be mapped but cannot be written except for dyna or sysweld)
Supported Quantity Type:
- nodal
- element wise nodal
- element integration points (reduced and full integration)
MESH POSITION ALIGNMENT
- Rough align: Used to bring equal meshes close to each other. Does nothing if meshes are already close
- Fine Align:
- align meshes for mapping. Sometimes the first iterations are not enough to bring meshes close. This button can be used several times in sequence to improve the result.
- Manually aligning by mouse is also possible. Use the mouse if the rough align gives a bad result.
- Restrictions:
- Rough aligning only works for similar geometries.
- Aligning doesn't work for partially overlapping models, even with manual prealigning
Mapping Quantities

Very few clicks to map all visible parts and active quantities
- Load a source mesh
- Load a target mesh
- Switch to quantity panel (optional)
- Select quantities which shall be mapped on target (optional)
- Switch to mesh panel (optional)
- Select meshparts that shall be mapped (optional)
- Press mapping button
- Switch to validation panel (optional)
- Press validation button for quantity validation (optional)
- Switch to analysis panel (optional)
- Press the analysis button for data analysis (optional)
- Save target to file
Validation

The Validation panel is designed for validating mapped and non-mapped quantity data on given source and target meshes. Supported functions are at this time
- Association distance: Shows the association distance of the current mapping position. The distance of the visible target parts to the visible source parts is calculated.
- Nodal distance: Shows the distance to the next node of the current mapping position. The distance of the visible target parts to the visible source parts is calculated.
Analysis and Comparison

The Analysis panel is disgned to examine tensor-quantities as strain and stress of (multi)layer shell data. At the moment supported layers are only surface layers, i.e. front and rear of a given plate.
Strain:
- Major strain of front layer
- Minor strain of front layer
- Equivalent/Mises strain of front layer
- Major strain of rear layer
- Minor strain of rear layer
- Equivalent/Mises strain of rear layer
Stress:
- Major stress of front layer
- Minor stress of front layer
- Equivalent/Mises stress of front laye
- Major stress of rear layer
- Minor stress of rear layer
- Equivalent/Mises stress of rear layer
