Using gmshToFoam to Convert 2D Mesh for OpenFOAM

Monday 27th November 2023

This is an important step in computational fluid dynamics (CFD) to use a mesh as per the software specifications. OpenFoam provides a command-line utility blockMesh to generate a mesh. Whereas, the gmsh generates a mesh in a variety of formats. Here, I follow the steps in [1] to generate and convert a mesh. Copy the example in 3.1. 2D plane-symmetric stenosis as mymsh11.geo and export it to mymsh11.msh file with the save parametric coordinates option. Use gmshToFoam application to generate the mesh for OpenFoam in the case directory. I used a copy of the elbow example case provided with the OpenFoam. For verification, see the directory polyMesh inside the constant directory, and also use the checkMesh utility.

The Department of Biomedical Engineering (BME) organized a two-day workshop on "Recent Trends in Medical Device Design and Development," as the Pakistan Engineering Council (PEC) Continued Professional Development (CPD) event. 

Day 2

In computing lab 5, the event started with the recitation from the Holy Quran by Engr. Shahid Hussain, Sr. Lecturer BME. Engr. Tayyaba Khalid was the first speaker. The title of her presentation was, "Implementation Architecture for Medical Device Design." She explained the implementation model through a selected process. The role of the Biomedical Engineer in the Design Process, Verification through the use of Computer Simulation, and Validation through User needs were emphasized. 

Engr. Hina Iftikhar, Lecturer BME was the second speaker. The title of her speech was, "Medical Device Functions through Unified Markup Language." She explained the usefulness of UML diagrams in medical device design and development. An emphasis was on the use of UML diagrams to prepare the specifications of medical devices for the product development team.

Engr. Shahid Hussain, Sr. Lecture BME was the third speaker. The title of his speech was, "Proposal Writing to Acquire Funds for Medical Device Research & Development." He explained the research process and important sections in the proposal to acquire funds for medical device design and development. 

Engr. Dr. Muhammad Faris, Assistant Professor & Program In-Charge BME was the fourth speaker. The title of his speech was, "Quality Standards for Medical Device Manufacturing." He explained the selected standards used by the medical device manufacturers.
