摘要：The visualization of results obtained with numerical analysis using methods such as the Finite Element Method is a problem that has been faced since the computational simulation is used in engineering. Post-processing of 2D or 3D geometry, vector (as velocities) and scalar (as stresses) variables is performed using features as colors according to the value, arrows indicating direction, mesh visualization, rotation and pan. To employ the virtual reality for post-processing the results, the user should write in the numeric analysis code an output routine in VRML (Virtual Reality Modeling Language) format. The VRML visualization is executed in internet browsers by installing free VRML navigation plug-ins, without needing commercial softwares. This work presents details of VRML language to visualize scalar variables and to make animation. Engineering examples and the software of scientific visualization in virtual reality in development are shown. An advantage of VRML is that any user without deep computer graphics knowledge is able to use it to visualize the results of numerical analysis.
