Sigrity-Celsius Thermal Solver User Guide.rar

celsiusgds.tcl reads gds database and generate model that Celsius3D can read. celsius3d.tcl import the model and generate other neccessary setup for stress simulation. model: chip connected to a silicon interposer by bump condition: temperature drop from 217C to 25C boundary condition: free thermal expansion of the model remarks: for demostration purpose, model used default coarse mesh. to generate finer mesh for more accurate simulation, user may change mesh seeding parameters in celsius3d.tcl or add other mesh control method in the model. run the full flow: run.sh
