Moldex3D/eDesign-Warp 

Moldex3D-Warp provides users a true 3D simulation tool to anatomize the causes of shrinkage and warpage and further control these defects before mold is built. With eDesign-Warp, users can easily and efficiently improve the part quality and optimize design. For fiber-filled material, eDesign-Warp incorporates fiber composite theories and the fiber orientation results from eDesign-Fiber to predict its anisotropic shrinkage and warpage. 


Based on the filling, packing and cooling analyses by Moldex3D/eDesign-Flow/Pack/Cool, Moldex3D/eDesign-Warp allows users to perform true 3D warpage analysis on thick parts and those parts that have extreme thickness changes. With eDesign-Warp, users can easily and efficiently improve the part quality and optimize design. For fiber-filled material, eDesign-Warp incorporates fiber composite theories and the fiber orientation results from eDesign-Fiber to predict its anisotropic shrinkage and warpage. Furthermore, eDesign-Warp links with eDesign-I2 modules to interface with structural analysis software. 

Capabilities
Moldex3D/eDesign-Warp allows you to:
- Evaluate final part shape before actual molding
- Evaluate both single cavity and multi-cavity molds 
Evaluate unbalanced cooling effect on warpage 
Evaluate volumetric shrinkage effect on warpage 
Evaluate molecular and/or fiber orientation effect on warpage (Moldex3D/eDesign-Fiber module is required to predict fiber orientation).
Evaluate in-mold constraint effect on warpage 
Evaluate moldbase thermal deformation effect 
Evaluate thermally induced residual stress 
Query any two points to determine the linear shrinkage ratio between two locations 
Define an arbitrary reference plane for easy measurement of deflection 
Separate total displacement into x-axis, y-axis, and z-axis displacements to show the deformation in each direction 
Export warpage shape in STL format or Moldex3D-Mesh format for further study 
Export inverse warpage shape in STL format or Moldex3D-Mesh format for further study

Features 

Part warpage analysis:
- Calculate final part shape due to material shrinkage as the temperature and pressure changes from the process settings to room conditions

Residual stress analysis:
- After part ejection, the part shrinks and deforms to an equilibrium shape. At this moment, the remaining stress inside the part is called process-induced residual stress 
- Calculate residual stresses developed during the entire molding cycle, including effects of temperature and pressure distributions, material orientation and geometric features 

Material anisotropic analysis:
- Anisotropic properties are calculated based on the material orientation tensors obtained from flow analysis 
- Anisotropic properties are calculated based the 
- material orientation tensors of flow analysis 
- Anisotropic properties are transferred to general structure CAE software for analyzing the part structure with process-induced properties. 

In-mold constraint effect analysis 
- Before the part is ejected, the deformation of warpage has been developed inside the mold. However, it can not shrink and deform freely due to constraints by the rigid mold. 
- Calculate the in-mold constraint induced part warpage to enhance the analysis accuracy.
