Multiscale.Sim is a customized product that based on the multi-physics analysis tool "Ansys," and provides the equivalent property values as the homogenization method that is based on the numerical material test. Also, it provides the multi-scale analysis feature that is required for micro/macro structure linking analysis such as the macro model analysis to the localized analysis.

Material property values are calculated by numerical material test of micro structure without material tests that were required conventionally, by utilizing Multiscale.Sim. The results enable prediction of the macroscopic behavior by the macro structural analysis. Further, it is possible to predict the microscopic behavior by going back to the micro structure analysis again.

Multiscale Analysis flow

Create a Micro Model Create a micro model using 3D CAD or Ansys DesignModeler for numerical material test.   Homogenization Analysis After mesh generation and entering the boundary conditions in Ansys, perform numerical material test and then calculate the equivalent property value such as elasticity modulus. Macro Structure Analysis (*figure shows a printed circuit board model) Apply the equivalent property value output from the homogenization analysis results as a material property of the macro model, then perform verification and analysis of macro model repeatedly.   Localization Analysis Verify the behavior of the local area by selecting the element selected to be localized from the macro analysis results and perform a localization analysis using the strain of that localized area as condition.
