Finite Element (FE) Model Simulation

Steps to compare Experiment to FE models:

  • Step 1: First, load experimental velocity data. Click on `Load Data <common_dialogs.html#data-loader>`_* to select an edited velocity data set from the database or from local disk.

  • Step 2: Secondly, select a model from database or disk. Simply click on Load Model and choose a model in the resulting dialog. If they exist, you will be given the choice of also loading noise vectors.

  • Step 3: Next, simulate the loaded model with a finite element solution by clicking Simulate Model.

  • Step 4: After simulation, a variety of options are available for displaying simulation results, residuals, and distributions. Report text files and graphics plot files can also be generated.

Simulation Product Output Summary:

When the “Simulate Model” button is clicked in the Finite Element Model Viewer window, a simulation is performed using the Edit data, a Loaded Model, and simulation parameters primarily created using the edit data set. A simulation data set is created that has the same ranges as the edit set, but with readings values that are calculated and compared to the actual experimental data. The comparison spawns a number of new dialogs and options that allow the user to evaluate the quality of the model.
