Automating this process not only saves time, but can increase reliability and scope of verification compared to ‘hand’ comparisons. Verifying that a local software installation performs as the developer intends is a potentially time-consuming but necessary step for nuclear safety-related codes. AlN nanowires exhibit a better piezoelectric response than LiNbO3 nanowires do.Īutomated Installation Verification of COMSOL via LiveLink for MATLABĭOE Office of Scientific and Technical Information (OSTI.GOV) The variation of the total maximum displacement as a function of applied force for various NWs lengths and the variation of the voltage as a function of applied force were plotted and discussed. The Finite Element Method (FEM) was used for solving the differential equations with various parameters such as size, length, force, etc. In this study, Lithium niobate (LiNbO3) and Aluminum nitride (AlN) nanostructures were designed and investigated using the COMSOL Multiphysics software for pressure sensing applications. Modeling of Lithium Niobate (LiNbO3) and Aluminum Nitride (AlN) Nanowires Using Comsol Multiphysics Software: The Case of Pressure SensorĪhmad, A. The full functionality of the interface was demonstrated to model transport processes, governed by extended Nernst-Plank equation, in Class H Portland cement samples in high pressure and temperature autoclaves simulating systems that are used to store captured carbon dioxide (CO2) in geological reservoirs. Benchmark comparisons show that the developed interface can be used to predict a variety of reactive-transport processes accurately. cement) using GEMS thermodynamic database formats. The interface allows modeling media with complex chemistry (e.g. The two standalone software packages are managed from the interface that uses a non-iterative operator splitting technique to couple the transport ( COMSOL) and reaction (GEMS) processes. BurkanĪn interface was developed between COMSOL MultiphysicsTM finite element analysis software and (geo)chemical modeling platform, GEMS, for the reactive-transport modeling of (geo)chemical processes in variably saturated porous media. Overall, both software packages provided the ability to solve multiphysics phenomena accurately.Ī COMSOL-GEMS interface for modeling coupled reactive-transport geochemical processesĪzad, Vahid Jafari Li, Chang Verba, Circe Ideker, Jason H. COMSOL provided a flexible model setup whereas ANSYS required coupling incompatible elements to transfer load between electromagnetic, fluid flow, and heat transport modules. Prediction of power Loss by both models was in close agreement (5-13% variation) and the predicted temperature profiles were similar. Comparison of the results from the COMSOL model with the results from a pre-developed and validated ANSYS model ensured accuracy of the COMSOL model. Numerical models were developed to simulate temperature profiles in Newtonian fluids during continuous flow microwave heating by one way coupling electromagnetism, fluid flow, and heat transport in ANSYS 8.0 and COMSOL Multiphysics v3.4.
