Finite element prediction system for welding and solidifying crack in virtual environment

The invention provides a finite element prediction system for welding and solidifying a crack in virtual environment, which relates to the technical field of finite element prediction software for welding and solidifying a crack, and the complex simulation and the prediction processes of welding and solidifying a crack are simplified into the simple operation and settings of an interface. A preliminary processing subsystem comprises an interface operating module, an MSC.Marc interface document module, a subprogram.f file module and an invocation MSC.Marc software executing and computing module, and a post processing subsystem comprises a MSC.Marc software computed result processing module, a MatrixVB function module, a Matlab software module and a graphic display module; a solidified crack predicting subsystem comprises a resistivity curve loading module, a judgment module and a result output module. The application of the invention enables a common welding engineering technician to carry out the numerical simulation and prediction for welding and solidifying a crack; the computed result is processed, and the storage space of a result file is decreased; the result file is converted into a file format convenient for graphic display, and the computed results of a temperature field and a stress strain field are visually displayed in a graphic form.
