Step Action
1 Select “Simulation 3D Using 64bit Simulator…” under the Simulation menu, 3D Simulation Parameters dialog box appears.
2 Click advanced button to check the boundary condition setting.
3 Click Spectrum button to check the spectral information setting.
4 Unselect Use Non uniform Mesh checkbox in the Nonuniform Mesh Parameters region. Click OK button to close the simulation parameters dialog box.
5 Repeat step 1 to open the 3D Simulation Parameters dialog box again. The current setting is for uniform mesh simulation, the mesh size is 0.005 μm . Under the mesh setting region, read the minimum memory requirement is:

175.75M bytes

6 Select Use Nonuniform Mesh checkbox in the Nonuniform Mesh Parameters region. Click OK button to close the simulation parameters dialog box.
7 Open the 3D Simulation Parameters dialog box. The current setting uses the non-uniform mesh. Read the memory usage is 54.28M bytes.
